Answer:
D
Step-by-step explanation:
12 cm,
Simply use Pythagora's theorem. The square of the hypotenuse = the sum of the squares of the other two sides
So, you get the square of the missing side by subtracting 5 squared from 13 squared, which gives 144.
Square root of 144 is the length of the missing side, i.e. 12 cm.

Bo paid with 1/2 of his paycheck about 1/5 of the remainder in savings. The rest of his paycheck he divided equally among the college accounts of his 3 children.
1. What fraction of his paycheck went into each child's account?
2. If bo deposited $400 in each child's account, how much money was in Bo's original paycheck?
Answers
Answer:for college, 1-1/2-1/5 = 3/10. Divided by 3 children, 3/10 /3 = 1/10
B. 400 = 1/10 of the total (from above), so 400 = x/10. x = 400*10 = 4000
Step-by-step explanation:
Answer:
1. 1/6 2. $2400
Step-by-step explanation:
If Bo had 1/2 of his paycheck leftover to divide among his 3 kids, 1/2 divided by 3 is 1/6.
If 1/6 of his paycheck is $400, then all 6/6 of his paycheck would be $2400.

Each year, ratings are compiled concerning the performance of new cars during the first 90 days of use. Suppose that the cars have been categorized according to whether a car needs warranty related repair (yes or no) and the country in which the company manufacturing a car is based ( in some country X or not in country X). Based on the data collected, the probability that the new car needs a warranty repair is .08, the probability that the car is manufactured by a company based in country X is .60, and the probability that the new car needs a warranty repair and was manufactured by a company based in country X is .025. Use this information to answer (a) Through (D)
a.)Suppose you know that a company based in country X manufactured a particular car. What is the probability that the car needs warranty repair?
b.)Suppose you know that a company based in country X did not manufacture a particular car. What is the probability that the car needs warranty repair?
c.)Are need for warranty repair and location of the company manufacturing the car independent?
Yes or NO or Not enough information
Answers
Answer:
1. 0.0417
2. 0.1375
3. no
Step-by-step explanation:
lets define:
A as the probability that a car needs a warranty repair.
B as probability taht the car is manufactured by a company that is based in country X
we have the
prob(A) = 0.08
prob(B) = 0.60
prob(A∩B) = 0.025
a. we are to calculate the probability taht a car manufactured in country X needs a warranty repair.
= p(AIB) =
[tex]P(\frac{AnB}{p(B)}) \\[/tex]
= 0.025/0.60
= 0.0417
2. Probability that car needs warranty repair given it was not manufactured in country X.
P(AIB')
= p(A∩B')/P(B')
= 0.08-0.025/1-0.60
= 0.055/0.40
= 0.1375
3. no, Need for warranty repair and location are not independent
The probability that the car needs warranty repair is 0.0417, the probability that the car needs warranty repair was not manufactured in company X is 0.1375 and no, there is no need for warranty repair and the location of the company manufacturing the car is not independent.

Market researchers wanted to know whether the placement of a new product on a supermarket shelf significantly increases the percent of shoppers who will buy the product. At Supermarket X, a new product was placed on the top shelf, and at Supermarket Y, the product was placed one shelf below the top shelf. To observe buying habits, the researchers selected a random sample of 364 shoppers at X and another random sample of 327 shoppers at Y. Of the selected shoppers at X, 15 bought the product, and of the selected shoppers at Y, 19 bought the product. Which of the following is the most appropriate method for analyzing the results?
a. A two-sample z-test for a difference in sample proportions.
b. A two-sample z-test for a difference in population proportions
c. A one-sample z-test for a sample proportion
d. A one-sample z-test for a population proportion
e. A one-sample z-test for a difference in sample proportions
Answers
Answer:
a. A two-sample z-test for a difference in sample proportions
Step-by-step explanation:
We are told that there are two supermarkets in the research named X and Y.
That a random number of shoppers were selected in each supermarket.
Thus means we have two different sample proportion.. Since a different number of people were randomly selected from each supermarket and a different number of people purchased the product.
Thus, we will have 2 sample proportions one for supermarket X and the other for supermarket Y.
In addition, the position of the product was different in both supermarkets.
Thus, we can say that this is a 2 sample Z-test for difference in their sample proportion.
The option that is most appropriate method for analyzing the results is that a two sample z test for a difference in population proportions.
What is a two sample z-test?A Two-Sample Z-test is known to be a kind of test that is often employed so as to make a comparison of the means of two samples to know and show if it is feasible that they are a product of the same population.
Conclusively, When a two sample z test is employed in the data given above, one can know and show the various difference that can be seen in population proportions.

Solve The Following Problems
Answers
Answer:
1A. y=13
1B. Top and bottom angle are 124 and side angles are 56
2A. y=15
2b. Left angle = 80 Right angle = 100
Step-by-step explanation:
1 equal both equations together then solve for y. plug in y to get the angles
2 add both equations together then equal it to 180 degrees then solve for y. plug in y to get the angles
Step-by-step explanation:
For 1A
2y + 98° = 9y + 7° < being vertically opposite angles >
9y - 2y = 98° - 7°
7y = 91°
y = 13°
For 1B
9y + 7° = 9 * 13° + 7° = 124°
2y + 98° = 2 * 13° + 98° = 124°
The angles which are unknown are also vertically opposite angles so let unknown angles be x then
124° + 124 ° + x +x = 360° { being complete turn }
248° + 2x = 360°
2x = 112°
x = 56°
so all angles are 124° , 124° , 56°, 56°
For 2A
6y - 10 + 6y + 10 = 180° ( being linear pair)
12y = 180°
y= 15°
For 2B
6y - 10 = 6 * 15 - 10 = 80°
6y + 10 = 6 * 15 + 10 = 100°

f(x)=−x 2 −4x−19 find f(-9)
Answers
Answer:
64
Step-by-step explanation:
The value of the function f(x) = x² −4x−19 at the value x = -9 will be 98.
What is a function?A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Given function is f(x) = x² −4x−19. The value of the function at f(-9) will be calculated as:-
f(x) = x² −4x−19
f(-9) = ( -9 )² - ( 4 x --9 ) - 19
f(-9) = 81 + 36 - 19
f(-9) = 98
Therefore, the value of the function f(x) = x² −4x−19 at the value x = -9 will be 98.
