Answer:
I'm pretty sure it would be B; go 2 units to the right and 12 units up.
Step-by-step explanation:
the question is asking for the percentage that got it right not the number of letters in the word, and 9 is the number of letters, and 12 is the number that got it right.
The correct data for 2 in coordinate grid will be from the origin, go 9units to the right and 12units up.
How to locate a point on graph?
To locate a point having coordinate (x,y) in graph, we have to go x direction right or left depending on the sign of x-coordinate(for right +,for left -), then we have to go y direction up or down depending on the sign of y-coordinate(for up +,for down -).
The graph is done by taking Number of letters in the word in x axis and Percentage of students who spelled the word correctly in y axis.
According to the table, it is clear that for data 2 Number of letters in the word is 9. so x=9
And Percentage of students who spelled the word correctly is 12
so y=12
So the coordinate of the point for data 2 is (9,12)
To locate the point (9,12) in coordinate grid we have to go 9units to the right in x axis and then we have to go 12units up in y axis direction.
Therefore The correct data for 2 in coordinate grid will be from the origin, go 9units to the right and 12units up.

O B. If AKLME APQR and APOR=ASTU, then AKLME ASTU.
C. AKLM: AKLM.
O D. If AKLME APOR, then APORE AKLM.
Answer:
B. If ΔKLM ≅ ΔPQR and ΔPQR ≅ ΔSTU, then ΔKLM ≅ ΔSTU
Step-by-step explanation:
The transitive property in general says ...
if a=b and b=c, then a=c
The transitive property of congruence replaces the equal sign with a congruence symbol, and replaces a, b, c with any geometric figure. Here, the geometric figures used are triangles KLM, PQR, and STU.
If ΔKLM ≅ ΔPQR and ΔPQR ≅ ΔSTU, then ΔKLM ≅ ΔSTU

Both the companies have a two-tier system where suppliers are approved in two separate phases. A company can move on to Phase II if they have passed the Phase I phase. Historical data points that for a startup company like yours, the chances of landing with a supplier contract with Ford Motor Company is 32% in Phase I while it is 64% in Phase II. However, for General Motors, the chances of success for Phase I is 68% and 36%. Using this information, calculate the following:
(a) What is the probability of your company becoming a successfully approved supplier to Ford Motor Company? Use a tree diagram and standard notations for full credit.(b) What is the probability of your company becoming a successfully approved supplier to General Motors? Use a tree diagram and standard notations for full credit.
Answer:
(a) The probability of the company becoming a successfully approved supplier to Ford Motor Company is 0.2048.
(b) The probability of the company becoming a successfully approved supplier to General Motors Company is 0.2448.
Step-by-step explanation:
A local startup company working on a smart dashboard camera system is bidding to be a supplier for both Ford Motor company and General Motors.
Both the companies have a two-tier system where suppliers are approved in two separate phases.
It is provided that a company can move on to Phase II if they have passed the Phase I phase.
(a)
The chances of landing with a supplier contract with Ford Motor Company is 32% in Phase I while it is 64% in Phase II.
That is:
P (Phase I) = 0.32
P (Phase II | Phase I) = 0.64
Consider the tree diagram below.
Compute the probability of the company becoming a successfully approved supplier to Ford Motor Company as follows:
P (Supplier to Ford Motor Company) = P (Phase II | Phase I) × P (Phase I)
[tex]=0.64\times 0.32\\=0.2048[/tex]
Thus, the probability of the company becoming a successfully approved supplier to Ford Motor Company is 0.2048.
(b)
The chances of landing with a supplier contract with General Motors is 68% for Phase I and 36% for Phase II.
That is:
P (Phase I) = 0.68
P (Phase II | Phase I) = 0.36
Consider the tree diagram below.
Compute the probability of the company becoming a successfully approved supplier to General Motors as follows:
P (Supplier to General Motors Company) = P (Phase II | Phase I) × P (Phase I)
[tex]=0.36\times 0.68\\=0.2448[/tex]
Thus, the probability of the company becoming a successfully approved supplier to General Motors Company is 0.2448.

Human visual inspection of solder joints on printed circuit boards can be very subjective. Part of the problem stems from the numerous types of solder defects (e.g., pad non-wetting, knee visibility, voids) and even the degree to which a joint possesses one or more of these defects. Consequently, even highly trained inspectors can disagree on the disposition of a particular joint. In one batch of 10,000 joints, inspector A found742that were judged defective, inspector B found745such joints, and1145of the joints were judged defective by at least one of the inspectors. Suppose that one of the 10,000 joints is randomly selected.
(a) What is the probability that the selected joint was judged to be defective by neither of the two inspectors? (Enter your answer to four decimal places.)
(b) What is the probability that the selected joint was judged to be defective by inspector B but not by inspector A? (Enter your answer to four decimal places.)
Answer:
a
The probability that the selected joint was judged to be defective by neither of the two inspectors is [tex]P(A' n B' ) = 0.8855[/tex]
b
The probability that the selected joint was judged to be defective by inspector B but not by inspector A is [tex]P(A' n B) =0.0403[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is [tex]n_s = 10000[/tex]
The number of outcome for inspector A is [tex]n__{A}} = 742[/tex]
The number of outcome for inspector B is [tex]n__{B}} = 745[/tex]
The number of joints judged defective by both inspector is [tex]n(A u B) = 1145[/tex]
The the probability that the selected joint was judged to be defective by neither of the two inspectors is mathematically represented as
[tex]P(A' n B' ) = 1 - P(A u B)[/tex]
Now
[tex]P(A\ u \ B) = \frac{n(Au B)}{n_s }[/tex]
substituting values
[tex]P(A\ u \ B) = \frac{1145}{ 10 000 }[/tex]
So
[tex]P(A' n B' ) = 1 - \frac{1145}{10 000}[/tex]
[tex]P(A' n B' ) = 0.8855[/tex]
the probability that the selected joint was judged to be defective by inspector B but not by inspector A is mathematically represented as
[tex]P(A' n B) = P(A \ u \ B) -P(A)[/tex]
Now
[tex]P(A) = \frac{n__{A}}{n_s}[/tex]
substituting values
[tex]P(A) = \frac{742}{10 000}[/tex]
So
[tex]P(A' n B) = \frac{1145}{10 000} - \frac{742}{10 000}[/tex]
[tex]P(A' n B) =0.0403[/tex]
If the gardener can fill the border with 30 flowers planted 12 inches apart, how far apart should the gardener plant 36 flowers instead?
Answer:
10 inches
Step-by-step explanation:
This inversely proportional function, the more flowers - the less distance.
Flowers = k/distance
30 = k/12
k = 30*12 = 360
Flowers = 360/distance
New number of flowers and new distance:
Flowers = 360/distance
36 = 360/distance
distance = 360/36= 10 (inches)

What is the measure of the whole angle?
Answer:
130
Step-by-step explanation:
60° + 70° = x
In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 60 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.
60 + 70 = x
→ Simplify
130 = x
x = 130°
Given y = 4x + 3, what effect does changing the equation to y = 4x - 3 have on the y-intercept?
A)
graph becomes steeper
B)
no change to y-intercept
C)
graph moves down 3 units
D)
graph moves down 6 units
Answer:
graph moves down 6 units
Step-by-step explanation:
Y intercept of a line is point on y axis where the line crosses the y-axis.
Since the line is of the slope intercept form y = mx+ c
where m is slope of line and c is y intercept
_________________________________________________
Equation of old line : y = 4x + 3
then for equation y = 4x + 3
m: 4 and c = 3
Thus y intercept is +3 unit above the X axis
_________________________________________________
Equation of new line : y = 4x - 3
Similarly based on above explanation
m: 4 and c = -3
Thus y intercept is +3 unit below the X axis.
Thus we can see that y intercept has moved downward
Lets calculate no. of units it moved downward
Distance between them is 3 - (-3) = 6 unit
Thus graph moved 6 units downwards.
Steepness of graph depends on slope of line. The slope is 4 for both the lines and hence there is no change in steepness.
Thus correct answer is graph moves down 6 units

Find the value of x in the
following parallelogram:
2x - 10
2x + 50
Answer:
the value of x = 35 ( NOT - 40 )
Step-by-step explanation:
In order to calculate the value of x in the following parallelogram: 2x - 10
2x + 50, we would have to calculate the following formula:
m<QPS+m<PQR=180°
According to the given data we have the following:
m<QPS=2x - 10
m<PQR=2x + 50
Therefore, 2x - 10+2x + 50=180
4x+40=180
x=140/4
x=35
The value of x is 35 because in a parallelogram sum of the two adjacent angles is equal to 180 degree
What is parallelogram?In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
As we know,
In a parallelogram sum of the two adjacent angles is equal to 180 degree
2x - 10 + 2x + 50 = 180
4x + 40 = 180
4x = 140
x = 35
Thus, the value of x is 35 because in a parallelogram sum of the two adjacent angles is equal to 180 degree

If b (middle term) is negative and c (last term is positive) then what do you know about the two factors? ex. 2x^2-7x+6
Answer:
signs of the constants in the binomial factors are negative
Step-by-step explanation:
Assuming the first term (a) is positive, the fact that c is negative means the constants in the binomial factors have the same sign. The negative b means that sign is negative.
2x^2 -7x +6 = (x -2)(2x -3)
__
Further comment
c is the product of the constants in the binomial factors so will be positive when both those constants have the same sign.
b is the sum of the constants in the binomial factors. If both factors have the same sign (c > 0), then those constants have the same sign as b.
In this analysis, "a" is assumed to be positive. If it is not, then the same analysis can be done after reversing all of the signs.
An advertising executive claims that there is a difference in the mean household income for credit cardholders of Visa Gold and of MasterCard Gold. A random survey of 1010 Visa Gold cardholders resulted in a mean household income of $50,930$ 50,930 with a standard deviation of $9500$ 9500. A random survey of 66 MasterCard Gold cardholders resulted in a mean household income of $45,720$ 45,720 with a standard deviation of $9800$ 9800. Is there enough evidence to support the executive's claim? Let μ1μ1 be the true mean household income for Visa Gold cardholders and μ2μ2 be the true mean household income for MasterCard Gold cardholders. Use a significance level of α=0.01α=0.01 for the test. Assume that the population variances are not equal and that the two populations are normally distributed.
Answer:
We conclude that there is no difference in the mean household income for credit cardholders of Visa Gold and of MasterCard Gold.
Step-by-step explanation:
We are given that a random survey of 10 Visa Gold cardholders resulted in a mean household income of $50,930 with a standard deviation of $9500.
A random survey of 66 MasterCard Gold cardholders resulted in a mean household income of $45,720 with a standard deviation of $9800.
Let [tex]\mu_1[/tex] = true mean household income for Visa Gold cardholders.
[tex]\mu_2[/tex] = true mean household income for MasterCard Gold cardholders.
So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu_1=\mu_2[/tex] {means that there is no difference in the mean household income for credit cardholders of Visa Gold and of MasterCard Gold}
Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu_1\neq \mu_2[/tex] {means that there is a difference in the mean household income for credit cardholders of Visa Gold and of MasterCard Gold}
The test statistics that would be used here Two-sample t test statistics as we don't know about the population standard deviations;
T.S. = [tex]\frac{(\bar X_1-\bar X_2)-(\mu_1-\mu_2)}{s_p\sqrt{\frac{1}{n_1} +\frac{1}{n_2} } }[/tex] ~ [tex]t__n__1-_n__2-2[/tex]
where, [tex]\bar X_1[/tex] = sample mean household income for Visa Gold cardholders = $50,930
[tex]\bar X_2[/tex] = sample mean household income for MasterCard Gold cardholders = $45,720
[tex]s_1[/tex] = sample standard deviation for Visa Gold cardholders = $9,500
[tex]s_2[/tex] = sample standard deviation for MasterCard Gold cardholders = $9,800
[tex]n_1[/tex] = sample of Visa Gold cardholders = 10
[tex]n_2[/tex] = sample of MasterCard Gold cardholders = 6
Also, [tex]s_p=\sqrt{\frac{(n_1-1)s_1^{2} +(n_2-1)s_2^{2} }{n_1+n_2-2} }[/tex] = [tex]\sqrt{\frac{(10-1)\times 9,500^{2} +(6-1)\times 9.800^{2} }{10+6-2} }[/tex] = 9,608.22
So, the test statistics = [tex]\frac{(50,930-45,720)-(0)}{9,608.22 \times \sqrt{\frac{1}{10} +\frac{1}{6} } }[/tex] ~ [tex]t_1_4[/tex]
= 1.05
The value of t test statistics is 1.05.
Now, at 0.01 significance level the t table gives critical values of -2.977 and 2.977 at 14 degree of freedom for two-tailed test.
Since our test statistic lies within the range of critical values of t, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region due to which we fail to reject our null hypothesis.
Therefore, we conclude that there is no difference in the mean household income for credit cardholders of Visa Gold and of MasterCard Gold.
