Answer:
3/7 (b)
Step-by-step explanation:
If a combination is picked at random with each possible locker combination being equally likely, the conditional probability P(B|A) is 3/7.
What is conditional probability?Conditional probability is defined as the likelihood of an event or outcome occurring, based on the occurrence of a previous event or outcome.
Probability of event A = P(the first digit is an odd number) = 4/8
Given that event A has already occurred, we need to calculate the probability of the occurrence of probability B.
The total possible outcomes are 7 (out of 8 one is used up in event A).
Favorable outcomes are 3 (out of 4 one is used up in event A).
P(B|A) = 3/7

Dylan has a square piece of metal that measures 17 inches on each side. He cuts the metal along the diagonal, forming two right triangles. What is the length of the hypotenuse of each right triangle to the nearest tenth of an inch?
Answer:
24 Inch
Step-by-step explanation:
When the square piece of metal is cut along the diagonal, it forms two right triangles where each of the right triangle has legs of 17 inches.
To determine the length of the hypotenuse, we use the Pythagorean Theorem.
[tex]\text{Pythagoras Theorem}: Hypotenuse^2=Opposite^2+Adjacent^2\\Hypotenuse^2=17^2+17^2\\Hypotenuse^2=289+289\\Hypotenuse^2=578\\Hypotenuse=\sqrt{578} \\=24.04\\\approx 24$ inch ( to the nearest tenth of an inch)[/tex]

What is the measure of Arc CB. How did you determine this?
Answer:
As shown in picture,
Angle CDF = Angle BDE = 54 deg (pair of opposite angles)
Angle CDB = 180 - CDF = 180 - 54 = 126 deg (BF is a diameter).
=> Arc CB = Angle CDB = 126 deg (property of angle on circle)

Nathan took his car in for service and repair. He had a coupon for 15% off. $261.36 $381.25 $77.52 Which amount is closest to Nathan's total costs after the 15% discount and 7% sales tax?
Answer:
Total amount to be paid = $655
Step-by-step explanation:
Given,
Total price before coupon is = 261.36 +381.25+77.52
= $720.13
Discount = 15%
Amount of discount = 15% of total amount
Amount of discount = [tex]\frac{15}{100} \times 720.13[/tex]
= $108.02
Remaining amount = Total amount - discount amount
Remaining amount = $720.13 - $108.02
= $612.11
Sales tax = 6%
Amount of sales tax = 6% of remaining amount
[tex]=\frac{6}{100} \times 612.11\\\\=42.85[/tex]
Amount to be paid = Remaining amount + sales tax
= 612.11 + 42.85
= 654.96
Rounding off to nearest whole number;
Total amount to be paid = $655

Choose the graph that represents the linear equation 6x - 2y = 12. *
9
Answer: x-intercept = 2, y-intercept = -6
Step-by-step explanation:
To solve this problem, we must first convert 6x - 2y = 12 to slope-intercept form by getting y by itself.
1. 6x - 2y = 12
2. -2y = 12 - 6x
3. -2y/-2 = 12/-2 - 6x/-2
y = 3x - 6
Using our knowledge of what the slope-formula represents, we know that the -6 is the y-intercept.
To find the x-intercept, we set the formula equal to 0 instead of y and solve for x.
1. 0 = 3x - 6
2. 0 + 6 = 3x
3. 6/3 = 3x/3
x = 2

What is the measure of angle b ?!
Answer:
the answer is 47
Step-by-step explanation:
first you would add the sum of angle A to the sum of angle D. next you would subtract 180 from 133 to get 47. then you can check your answer by adding 34 and 47 which is 81 and then subtract that from 180 to get the measure of angle D.
34+99=133: 180-133=47
34+47=81: 180-81=99

a rectangle is reduced by a scale factor of 1/4 which choices show the ratio of the area hurry because i need this for a test
Aleecha107Junior Moderator
Answer:
The area would be 1 : 16 ratio, of the smaller rectangle to the larger one.
Step-by-step explanation:
I used a rectangle with the side length of 1 to model this for me. You can choose any number, but 1 is easy to multiply.
If the original rectangle had a side length of 1 and 1, the area would be 1.
If you reduce the size to 1/4th of the size, the area would be 0.0625, or 1/16th of the original.

In the U.S., approximately 8.3% of the population has diabetes. Maryland's rate of diabetes for its residents is 12% higher than the national average. What is the rate of diabetes in the state of Maryland? *
Answer:
9.30%
Step-by-step explanation:
Given;
The average rate in the national average N = 8.3%
The average rate in Maryland R = 12% higher than national
R = N + 12% of N
R = N + 0.12N
R = 1.12N
R = 1.12 × 8.3%
R = 9.296%
R = 9.30%
Rate of diabetes in Maryland = 9.30%
The ratio of yes votes to no votes was 5 to 7. If there were 10,092 total votes, how many yes votes were there?
Answer:
4,205
Step-by-step explanation:
5 + 7 = 12
10,092 ÷ 12 = 841
multiplier for the ratio is therefore 841.
5:7 is yes:no
since you want the number of yes votes, u take the 5 and multiply it by the multiplier found before.
5 × 841 = 4,205 yes votes.

Ms. Ahmed has a rectangular garden where she grows tomatoes. The length of her garden is represented by t + 4 and the width by 2t - 1. Express the area of Ms. Ahmed's garden as a polynomial in standard form. If the area of Ms. Ahmed's garden is 56 ft2, what are the dimensions of the garden?
Answer:
Area of the garden in standard form:
Area = (2t^2) + 7t - 4
The dimension of the garden is 8ft × 7ft
Step-by-step explanation:
Length of the rectangular garden, L = t+4
Width of the garden, B = 2t - 1
Area = length * width
Area = (t+4) * ( 2t-1)
Area = (2t^2) + 7t - 4..….......(1)
If the Area = 56 ft^2
Substitute Area into (1)
56 = (2t^2) + 7t - 4
(2t^2) + 7t - 60 = 0
(2t^2) - 8t + 15t - 60 = 0
2t(t - 4) + 15(t - 4) = 0
(2t+15) (t-4) = 0
Let 2t + 15 =0
t = -7.5
Let t - 4 = 0
t = 4
* When t = -7.5
Length, L = -7.5 + 4 = -3.5 ft
Width, B = 2(-7.5) -1 = -16 ft
Since length and breadth cannot be negative, t = -7.5 is not possible
** When t = 4
Length, L = 4+4 = 8 ft
Width, B = 2(4) - 1 = 7 ft
Therefore, the dimension of the garden is 8ft × 7ft
Answer:
The dimension is 8ft by 7ft
Step-by-step explanation:
Given data
Length l = [tex](t+4)[/tex]
Width w= [tex](2t-1)[/tex]
the area is expressed as [tex]A= length * width[/tex]
[tex]A= (t+4)*(2t-1)\\A= t(2t-1) +4(2t-1)\\A= 2t^{2}-t+8t-4\\[/tex]
collecting like terms we have
[tex]A= 2t^{2} +7t-4[/tex]
hence our expression for area is [tex]A= 2t^{2} +7t-4[/tex]
given that the area is [tex]56ft^{2}[/tex] to solve for the sides we need to first solve fot t
equating the expression for area to 56 we can solve for t
[tex]A= 2t^{2} +7t-4= 56[/tex]
taking the constant term to the other side and solve we have
[tex]A= 2t^{2} +7t-4-56\\A= 2t^{2} +7t-60\\[/tex]
we can substitute two factors for 7t that when multiplied we give -60 and when added we give 7 these factors are 15 and -8
[tex]A= 2t^{2} +7t-60\\\\A= 2t^{2} -8t+15t-60\\2t^{2} -8t+15t-60=0\\\\2t(t-4) +15(t-4)= 0\\2t+15=0, (t-4)= 0\\2t=-15, t= -7.5\\t= 4[/tex]
t=4 hence the length is
[tex](t+4)\\(4+4)= 8ft\\[/tex]
hence the width is
[tex](2t-1)\\(2*4-1)= (8-1)= 7ft[/tex]

A) concert attendance
B) age of a student
C) number of pens in a box
D) time taken to run 1 mile
Answer:
Age of a student (B) and Time taken you run 1 mile (D)
Step-by-step explanation:
Only the age of a student and the time taken to run 1 mile are continuous data.
What are the types of data?
The data is classified into majorly four categories:
Nominal data: Nominal Data is used to label variables without any order or quantitative value.Ordinal data: Ordinal data have natural ordering where a number is present in some kind of order by their position on the scale. Discrete data: The term discrete means distinct or separate. The discrete data contain the values that fall under integers or whole numbers.Continuous data: Continuous data are in the form of fractional numbers. It can be the version of an android phone, the height of a person, the length of an object, etc. Continuous data represents information that can be divided into smaller levels. The continuous variable can take any value within a range.As per the given definitions above we can state that Continuous data is (B) the Age of the students (D) the Time taken to run 1 mile
Therefore, the Answer is (B) and (D)

A sporting equipment company wants to sell a new bicycle helmet. They have developed a function, shown below, where total profit, p, can be determined based on sale price, s.
What will be the total profit if the sale price of the helmet is $60?
Answer:
[tex] p(s) = -24s^2 +2200 s -18000[/tex]
If we use the valie of s =60 we have
[tex] p(60) = -24 (60)^2 +2200*60 -18000[/tex]
And after solve we got:
[tex] p(60)= -86400 +132000 -18000 =27600[/tex]
So then the best option for this case would be:
$27,600
Step-by-step explanation:
Using the following info in order to complete the problem:
p(s)=-24s^(2)+2200s-18000
$112,560
$27,600
$111,120
$236,400
$14,240
We have the following function given:
[tex] p(s) = -24s^2 +2200 s -18000[/tex]
If we use the valie of s =60 we have
[tex] p(60) = -24 (60)^2 +2200*60 -18000[/tex]
And after solve we got:
[tex] p(60)= -86400 +132000 -18000 =27600[/tex]
So then the best option for this case would be:
