Answer:
12.4 pieces of ribbon
Step-by-step explanation:
When looking in the question, we can see the term "cut into equal pieces." This can insure to us that we need to divide two numbers. Since we originally have 15.5 inches long string, and we want to cut it into strings that are 1.25 inches long. We divide :
15.5 / 1.25
==> 12.4

There are 4 roses in a vase of 13 flowers the rest are daisies what is the ratio of all flowers in the vase to daises
Answer:
The ratio is 13:9
Step-by-step explanation:
Since the rest of the flowers in the vase are daisies, subtract the 4 roses from the 13 flowers. 13 - 4 = 9
There will be 9 daisies in the vase in total. Then they are asking for you to put the ratio of the total flowers to the daisies.
Total Flower = 13
Daisies = 9
The ratio would be 13 to 9.
The ratio of all flowers in the vase to daises is [tex]13:9[/tex]
Let the flowers be F.Let the daisies be D.Given the following data:
Number of roses = 4 rosesNumber of flowers = 13 flowersTo determine the ratio of all flowers in the vase to daises:
First of all, we would solve for the number of daisies in the vase of flowers.
[tex]Number\;of\;daisies = 13-4[/tex]
Number of daisies = 9 daisies.
Now, we can find the ratio of all flowers in the vase to daises:
[tex]Ratio = F:D\\\\Ratio = 13:9[/tex]

write the equation of the line in slope intercept form that passes through (10,21) and (15,36)
Answer:
y = 3x - 9
Step-by-step explanation:
First, find the slope using rise/run (y2 - y1) / (x2 - x1)
Plug in the points:
(36 - 21) / (15 - 10)
15/5
= 3
Next, plug the slope and a point into the equation y = mx + b to find b (y-int)
y = mx + b
21 = 3(10) + b
21 = 30 + b
-9 = b
Then, plug this into the equation, as well as the slope:
y = 3x - 9

If f(x) = -3x + 4 and g(x) = 2, solve for the value of x for
which f(x) = g(x) is true.
Ya
f(x) = g(x)
-3x+4 = g(x) ... f(x) replaced with -3x+4
-3x+4 = 2 .... g(x) replaced with 2
-3x+4-4 = 2-4 .... subtract 4 from both sides
-3x = -2
-3x/(-3) = -2/(-3) .... divide both sides by -3

The independent variable of interest in an ANOVA procedure is called a a. partition. b. factor. c. treatment. d. response.
Answer:
Option b (factor) is the correct choice.
Step-by-step explanation:
ANOVA would be used to assess whenever there were other statistically representative variations seen between results of two or even more individual (totally unconnected) categories.
Two different kinds of independent variables exist such as:
ActiveReferenceIf the explanatory variables are such an effective variable otherwise we modify the argument of the variable to test its effect on something like a specific parameter.
Certain solutions don't apply to the specified scenario. So choice B was its perfect method for that.

Assume two independent random samples are available which provide sample proportions. For the first sample assume n1= 100 and x1= 39. For the second sample, assume n2= 100 and x2= 49. Test the null hypothesis that the population proportions are equal versus the alternative hypothesis that the proportions are not equal at the 90% confidence level. Frame the test statistic by subtracting the proportion for population 1 from that for population 2. Pick an appropriate z value, p-value and conclusion. Round your answer to the nearest thousandth.
a) z-value = -1.425 p-value= 0.077 statistically significant
b) z-value = 1.425 p-value= 0.077 not statistically significant
c) z-value = 1.425 p-value= 0.077 statistically significant
d) z-value = -1.425 p-value= 0.1543 not statistically significant
Answer:a) z-value = -1.425 p-value= 0.077 statistically significant
Step-by-step explanation:
Given the following :
n1 = 100; x1 = 39 ; n2 = 100 ; x2 = 49
Z value for two independent samples can be obtained using the relation :
Z = (p1 - p2) /(√p(1-p)) * (√[(1/n1) + (1/n2)]
Z = -1.425
P-value : using the online p-value calculator at a confidence level of 90% from z score
Obtained p value = 0.077079
The p value is less than 0.1 , hence result is significant at p<0.10

Answer:
The probability is [tex]P(12.7 < x < 16.8 ) = 0.45[/tex]
Step-by-step explanation:
From the question we are told that
The completion times for a job task range from 10.1 minutes to 19.2 minutes
Generally given that the completion times is uniformly distributed then the probability that it will require between 12.7 and 16.8 minutes is mathematically represented as
[tex]P(12.7 < x < 16.8 ) = \frac{ 16.8 - 12.7}{ 19.2 - 10.1 }[/tex]
[tex]P(12.7 < x < 16.8 ) = 0.45[/tex]
use pythagorean theorem to find the length of the hypotenuse in the triangle shown below 11 and 60
Answer: The value of the hypotenuse is 61.
Step-by-step explanation:
So we are given a triangle with two known sides; two legs with values of 11 and 60. We have to use the Pythagorean Theorem to find the value of the hypotenuse.
The Pythagorean Theorem states that, "the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides".
This means that:
a^2 + b^2 = c^2
leg^2 + leg^2 = hypotenuse^2
So just by looking at that, we know that we can just substitute the values in:
11^2 + 60^2 = x^2
121 + 3600 = 3721
sqrt of 3721 = 61
So the hypotenuse value is 61.
A man drove 14 mi directly east from his home, made a left turn at an intersection, and then traveled 5 mi north to his place of work. If a road was made directly from his home to his place of work, what would its distance be to the nearest tenth of a mile?
Answer:
14.9 miles
Step-by-step explanation:
If the road was created, the 3 different roads would form a right triangle where the new road would be the hypotenuse and the other 2 roads would be the legs.
We can use the pythagorean theorem to find the length of the hypotenuse, or the new road:
a² + b² = c²
14² + 5² = c²
221 = c²
14.9 = c
= 14.9 miles
15 ‒ 5x = 6x + 3 – 2x
Answer:
x = 4/3
Step-by-step explanation:
15 - 5x = 6x + 3 - 2x
In this kind of equation, we try to seperate the x's and the numbers.
So we add 5x to both sides and subtract 3 from both sides to seperate these values
15 - 3 - 5x + 5x = 6x + 3 - 3 - 2x + 5x
=> 12 = 9x
=> 12/9 = x
=> 4/3 = x
=> x = 4/3
To check, we can plug this in.
15 - 5(4/3) = 6(4/3) + 3 - 2(4/3)
15 - 20/3 = 24/3 + 3 - 8/3
45/3 - 20/3 = 24/3 + 9/3 - 8/3
25/3 = 25/3
So our answer works.

Find the equation of the line that goes through (2,9) and (-1,5) in point-slope form
Answer:
y-9=4/3(x-2)
Step-by-step explanation:
First, find your slope:
The formula for finding slope is [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].
Our coordinate point for our x₁ and y₁ values will be (2,9) and our coordinate point for our x₂ and y₂ values will be (-1,5). Now, let's plug those into our formula:
[tex]m=\frac{5-9}{-1-2}=\frac{-4}{-3}=\frac{4}{3}[/tex]
Your slope is 4/3.
Next, plug in your x₁ and y₁ values in for point-slope form. The equation in variable form is "y-y₁=m(x-x₁)". So, plugging in our point (2,9) for x₁ and y₁, we get:
y-9=4/3(x-2)

A bank is designing a new branch office and needs to determine how much driveway space to allow for cars waiting for drive-up teller service. How many spaces should be provided to have a 96 percent probability of accommodating all of the waiting cars
This question is incomplete, the complete question is;
A bank is designing a new branch office and needs to determine how much driveway space to allow for cars waiting for drive-up teller service.
The drive-up service will have three tellers and a single waiting line. At another branch of the bank in a similar setting, the average service time for drive-up tellers is four minutes per customer, and average arrival rate is 36 customers per hour. It is expected that the new bank will have similar characteristics.
How many spaces should be provided to have a 96 percent probability of accommodating all of the waiting cars?
Answer:
Eleven (11) spaces should be provided to have a 96 percent probability of accommodating all of the waiting cars
Step-by-step explanation:
Given that:
the average service time for drive-up tellers is four (4) minutes per customer at each branch
Average number of customers per hour is 36
Therefore for 36 customers,
the branch can give ( 36 / 4 ) = 9, mins each customer
from the question, there is a probability of 96%
so we will calculate on the 9 as mentioned above
96% of 9 = 0.96
0.96 × 9= 8.64
If there are 3 tellers in a single line- , then
8.64 + 3 = 11.64 approximately 11
Therefore Eleven (11) spaces should be provided to have a 96 percent probability of accommodating all of the waiting cars
