Answer:

True

Step-by-step explanation:

The phrase is stated correctly the way that it is written so the answer you are looking for is True. The Phrase can also be stated numerically in the following way

$y = 11+0.20x$

The above equation would be the numerical translation of the phrase stated in the question. Although the equation cannot be solved without replacing the variable for a numeric value.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

K= 35.50x + 42<br> k=991x + 27

SSSSS [86.1K]

Answer:

k=42.5573 and x=0.015699

Step-by-step explanation:

Step: Solve k=35.5x+42for k:

k=35.5x+42

Step: Substitute 35.5x+42 for k in k=991x+27:

k=991x+27

35.5x+42=991x+27

35.5x+42+−991x=991x+27+−991x(Add -991x to both sides)

−955.5x+42=27

−955.5x+42+−42=27+−42(Add -42 to both sides)

−955.5x=−15

−955.5x

−955.5

−15

−955.5

(Divide both sides by -955.5)

x=0.015699

Step: Substitute0.015699 for x in k=35.5x+42:

k=35.5x+42

k=(35.5)(0.015699)+42

k=42.5573(Simplify both sides of the equation)

Hope this helps!

A sample of 5 buttons is randomly selected and the following diameters are measured in inches. Give a point estimate for the pop

Helen [10]

Answer:

$s^2 = \frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}$

But we need to calculate the mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_I}{n}$

And replacing we got:

$\bar X = \frac{ 1.04+1.00+1.13+1.08+1.11}{5}= 1.072$

And for the sample variance we have:

$s^2 = \frac{(1.04-1.072)^2 +(1.00-1.072)^2 +(1.13-1.072)^2 +(1.08-1.072)^2 +(1.11-1.072)^2}{5-1}= 0.00277\ approx 0.003$

And thi is the best estimator for the population variance since is an unbiased estimator od the population variance $\sigma^2$

$E(s^2) = \sigma^2$

Step-by-step explanation:

For this case we have the following data:

1.04,1.00,1.13,1.08,1.11

And in order to estimate the population variance we can use the sample variance formula:

$s^2 = \frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}$

But we need to calculate the mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_I}{n}$

And replacing we got:

$\bar X = \frac{ 1.04+1.00+1.13+1.08+1.11}{5}= 1.072$

And for the sample variance we have:

$s^2 = \frac{(1.04-1.072)^2 +(1.00-1.072)^2 +(1.13-1.072)^2 +(1.08-1.072)^2 +(1.11-1.072)^2}{5-1}= 0.00277\ approx 0.003$

And thi is the best estimator for the population variance since is an unbiased estimator od the population variance $\sigma^2$

$E(s^2) = \sigma^2$

A gym has 2kg and 5kg weights. There are 10 disks in all. The total weight of 2kg and 5kg disks is equal to 29kg. Find the numbe

Simora [160]

Answer:

no of 5 kg disks is 3, and no of 2 kg disks is (10-3) i.e. 7

Step-by-step explanation:

Let the no of 2kg disks be a.

Let no of 5 kg disks be b.

2a+5b=29

a+b=10

Using substitution, we have

2(10-b) + 5b=29

20-2b+5b=29

20+3b=29

3b=9

b=3

So no of 5 kg disks is 3, and no of 2 kg disks is (10-3) i.e. 7

(will give brainliest!!)

Alex73 [517]

Hey there!

To figure out what "x" means, you can divide the numbers 126 and 14 . . .

126 divided by 14 = 9

9 x 14 = 126

9 = x

----------------
x = 9
----------------

Hope this helps you.
Have a great day!
