Answer:

64

Step-by-step explanation:

The value of the function f(x) = x² −4x−19 at the value x = -9 will be 98.

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.

None of the choices has a slope of 1/7

Answer:

When graphing the function y = f(x+3), all of the x values would be shifted to the right by 3 because the transformation is a shift right by 3 units.

When graphing the function y=−f(x), there is a reflection over the y-axis

When graphing the function y=2f(x), all of the y-values would be multiplied by 2 because the transformation is a vertical compression by a factor of 2.

Note: "multiplied by 12" considered as typo otherwise this is to be included as correction

Answer:

the answer is A When graphing the function

y=f(x+3)

to find common ratio (r)

= second term÷first term

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.

Given :

a) The probability that the car needs warranty repair is given by:

[tex]\rm P(A|B) = \dfrac{ P(A\cap B)}{P(B)}[/tex]

[tex]\rm P(A|B) = \dfrac{0.025}{0.60}[/tex]

P(A|B) = 0.0417

b) The probability that the car needs warranty repair was not manufactured in company X is given by:

[tex]\rm P(A|B') = \dfrac{ P(A\cap B')}{P(B')}[/tex]

[tex]\rm P(A|B') = \dfrac{0.08-0.025}{1-0.60}[/tex]

P(A|B') = 0.1375

c) No, there is no need for warranty repair and the location of the company manufacturing the car is not independent.

Answer:

167y/3

Step-by-step explanation:

x=24-y

x=100/3-5y/3

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°

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.

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.
