What does x =? Solve for x

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:

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:

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.

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

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

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.

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]

Answer:

x^6

Step-by-step explanation:

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

f(g(x) = -3v
