Find the value of X. What does X=?

Answer:

Yes, because they add up to 360

Step-by-step explanation:

Answer:

The answer is D

29/3 = 9.6 (.6 is repeating)

√94 = 9.69

49/5 = 9.8

9.8 (.8 is repeating)

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

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)

I had the same question and I got it correct

Answer:

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:

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

Big Brain Dude <:

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:

option c is the correct answer

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!

Step-by-step explanation:

48 square inches indicates the base area of the prism

the base area can be find in this way = dim 1 x dim 2. If we multiply 12 x 4 we can find 48 squares inches

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:

The relative frequency of the last class interval is 0.2.

Step-by-step explanation:

Relative frequency:

The relative frequency of an interval is the size of the interval divided by the total size of the sample.

10 out of 50 items:

So the relative frequency is:

10/50 = 0.2

The relative frequency of the last class interval is 0.2.

b

Step-by-step explanation:

b would be correct because 33 is odd
