Answer:

8. h( f(x) ) = x²+14x+52

9. h( g(x) ) = 2x

Step-by-step explanation:

These questions are asking you to sub a function into another, and you solve by doing that the same way you would with a number. For example, if question 8 was h(3) instead of h(f(x)), you would sub 3 into h(x) wherever you saw an x, and evaluate. It's the same idea here, just with functions.

8.

h(x)=x²+3

h( f(x) ) = ( f(x) )²+3

h( f(x) ) = ( x+7 )²+3

h( f(x) ) = ( x²+14x+49 )+3

h( f(x) ) = x²+14x+52

9.

h(x)=x²+3

h( g(x) ) = ( g(x) )²+3

h( g(x) ) = ( [tex]\sqrt{2x-3}[/tex] )²+3

h( g(x) ) = (2x-3)+3

h( g(x) ) = 2x

Answer:

(3, 4)

Step-by-step explanation:

First, find the x coordinate of the midpoint by finding the average of the two x values:

(2 + 4) / 2

6 / 2

= 3

Find the y coordinate of the midpoint by finding the average of the two y values:

(3 + 5) / 2

8 / 2

= 4

So, the x coordinate of the midpoint is 3 and the y coordinate is 4.

The midpoint is (3, 4)

Answer:

Test statistic = - 2.33

Pvalue = 0.010 (3 decimal places)

Step-by-step explanation:

Given :

H0: p = 0.25 vs Ha: p < 0.25

Phat = 0.15

Sample size, n = 102

α = 0.05

The test statistic :

(Phat - p) / (√p(1 - p) /n)

1 - p = 1 - 0.25 = 0.75

(0.15 - 0.25) / (√0.25(0.75) /102)

-0.1 / √0.0018382

-0.1 / 0.0428742

Test statistic = - 2.33

The Pvalue using the test statistic score obtained :

P(Z < - 2.33) = 0.0099031 = 0.010

Pvalue < α ; Reject H0

Answer:

8 miles

Step-by-step explanation:

Given: A runner can run 5 miles in 26 minutes, 41.6 minutes = ___

To find: At this rate, how many miles can he run and 41.6 minutes?

Solution: If the runner ran 5 miles in 26 minutes, to find how far he ran in 41.6 minutes, set up a fraction:

let x be the variable

[tex]\frac{26}{5} = \frac{41.6}{x}[/tex]

Apply fraction cross multiply;

[tex]26x=5\cdot \:41.6[/tex]

[tex]26x = 208[/tex]

Divide both sides by 26

[tex]\frac{26x}{26}=\frac{208}{26}[/tex]

Simplify

[tex]x = 8[/tex]

Then, at the rate, the runner ran 8 miles 41.6 minutes

Answer:

The expected number of defective batteries to be pulled out is 0.9, which rounded to the nearest integer gives a total of 1, that is, 1 of the 3 batteries is expected to be defective.

Step-by-step explanation:

Given that a box contains 3 defective batteries and 7 good ones, and I reach in and pull out three batteries, to determine what is the expected number of defective batteries, the following calculation must be performed:

3 + 7 = 100

3 = X

10 = 100

3 = X

3 x 100/10 = X

300/10 = X

30 = X

3 x 3/10 = X

0.9 = X

Therefore, the expected number of defective batteries to be pulled out is 0.9, which rounded to the nearest integer gives a total of 1, that is, 1 of the 3 batteries is expected to be defective.

Answer:

a(6) = 2 [tex]\sqrt{3}[/tex] , b(10) = 15 [tex]\sqrt{2}[/tex]

Step-by-step explanation:

A. a(x) = [tex]\sqrt{2x}[/tex]

a(6) = [tex]\sqrt{2(6)}[/tex]

a(6) = [tex]\sqrt{12}[/tex]

a(6) = [tex]\sqrt{4}\sqrt{3}[/tex]

a(6) = 2 [tex]\sqrt{3}[/tex]

B. b(x) = 3 [tex]\sqrt{5x}[/tex]

b(10) = 3 [tex]\sqrt{5(10)}[/tex]

b(10) = 3 [tex]\sqrt{50}[/tex]

b(10) = 3 [tex]\sqrt{25}[/tex] [tex]\sqrt{2}[/tex]

b(10) = 3 x 5 [tex]\sqrt{2}[/tex]

b(10) = 15 [tex]\sqrt{2}[/tex]

H0 : The true average DNA content is not affected by the type of carbohydrate in the diet between samples

Ha : The true average DNA content is affected by the type of carbohydrate in the diet between samples

F(4,0) at 0.05 level of significance =0.5

As calculated F=0.001 >0.5

So, H0 is rejected, Hence the true average DNA content is affected by the type of carbohydrate in the diet between samples

For the first problem, you can convert [tex]-1 \frac{7}{10}[/tex] as a decimal, which is [tex]-1.7[/tex]. I've attached an image below and the red dot should be correct plotted version.

For the second problem, you can say something like Remy should look at the mixed fraction separate when plotting a mixed fraction. That way, it'll be easier to plot.

Hope this helps :) Let me know if you have any other questions with this problem!

Answer:

AD = 3

Step-by-step explanation:

Pythagoras theorem formula: a² + b² = c² (c being the hypotenuse, the longest side of the triangle).

Using this formula, you can easily say that c²-b²=a². c=5, b=4, making the equation 5² - 4² = a ².

Expanding the formula, you'll get 25 - 16 = a².

25 - 16 = 9.

This means that 9 = a².

To find a, you need to root 9. Using a calculator, you'll know that this number is 3, meaning that AD = 3.

Answer:

48 goes into 123 about 2.5625 times.

Step-by-step explanation:

To determine how many times does 48 go into 123, the following mathematical calculation must be performed, by which 123 will be divided by 48 to obtain said number of times:

123/48 = X

2.5625 = X

Therefore, 48 goes into 123 about 2.5625 times.
