Answer:

81 or [tex]3^{4}[/tex]

Step-by-step explanation:

[tex]3^{2} * 3^{2}[/tex]

(3 x 3) x ( 3 x 3)

9 x 9

81

The square root means to multiply a number by itself, and in this case, it's 3.

Keep the number 3 the same, and add up the exponents  and it gives u [tex]3^{4}[/tex]

Hope this helped!

                                                      Question 1)

Given

The expression is 5xy

To determine

Find the value of 5xy if x = 2 and y = 3

5xy

substitute x = 2 and y = 3

5xy = 5(2)(3)

      = 5(6)

      = 30

Therefore, the value of 5xy = 30 if x = 2 and y = 3.

Note: your remaining questions are not mentioned. But, the procedure may remain the same. Hopefully, your concept will be cleared anyway.

Answer:

-2 < x ≤ 6

Step-by-step explanation:

This graph shows conjunction. This means that the two statements of the inequality bare true at the same time. Therefore, it follows that:

x > -2 ("we use greater than" because the empty/unshaded circle indicates that -2 is not included)

And

x ≤ 6 (we use greater than or equal to because the shaded circle indicates 6 is included)

Joining both statements together, we would have:

-2 < x ≤ 6

The y-coordinate that represents the solution to the system of equations is 4

The equations are given as:

[tex]-x+y=1[/tex]

[tex]3x-y=5[/tex]

Make x, the subject in the first equation

[tex]-x+y=1[/tex]

[tex]x = y - 1[/tex]

Substitute y - 1 for x in the second equation

[tex]3x-y=5[/tex]

[tex]3(y - 1) - y = 5[/tex]

Open the brackets

[tex]3y - 3- y = 5[/tex]

Collect the like terms

[tex]3y - y = 5+3[/tex]

Evaluate the like terms

[tex]2y = 8[/tex]

Solve for y

[tex]y = 4[/tex]

Hence, the y-coordinate is 4

Answer:

 The 99% confidence interval for the mean repair cost for the VCRs

(65.801, 85.199)

Step-by-step explanation:

Explanation:-

Mean of the sample(x⁻) = $75.50

Given the standard deviation of the sample (S) =  $18.07

Given the size of the sample 'n' = 22

Degrees of freedom = n-1 =22-1 =21

critical value t₍₀.₀₁, ₂₁₎ = 2.5176

The 99% confidence interval for the mean repair cost for the VCRs

[tex](x^{-} - t_{0.01} \frac{S.D}{\sqrt{n} } , x^{-} +t_{0.01} \frac{S.D}{\sqrt{n} })[/tex]

[tex](75.50 - 2.5176 \frac{18.07}{\sqrt{22} } , 75.50 +2.5176 \frac{18.07}{\sqrt{22} })[/tex]

( 75.50 - 9.699 , 75.50 + 9.699 )

(65.801, 85.199)

Final answer:-

0.4 as a whole number would 1

The number 4 cannot be rounded down to 0 because 0 is not bigger or the same as 0. 4

Instead, the number 0. 4 would be rounded up to 1, which is the closest whole number.

A whole number is a positive number that doesn't have any parts with decimals or fractions. Whole numbers are numbers that start from 0 and go up without any fractions or negative numbers. In simpler terms, whole numbers include the numbers 0, 1, 2, 3, 4, 5, and so on. They only have positive numbers and whole numbers.
