Step-by-step explanation:

Step 1: Define

1/3z = -5

Step 2: Solve for z

Multiplication Property of Equality [Multiply both sides by 3]: 3 · 1/3z = -5 · 3
Simplify [Multiply]: z = -15

Step 3: Check

Plug in z into the original equation to verify it's a solution.

Substitute in z: 1/3(-15) = -5
Multiply: -5 = -5

Here we see that -5 does indeed equal -5.

∴ z = -15 is the solution to the equation.

Answer:

The money Rachael plan to collect for the shelter is $345.

Step-by-step explanation:

There are some data missing in the question, so below is the complete question:

Rachel is collecting donations for the local animal shelter. So far she has collected $245, which is 70% of what she hopes to collect. How much money does Rachel plan to collect for the shelter?

Now, to find the money Rachael plan to collect for the shelter.

Let the total money Rachael plan to collect be $x.$

The amount far she has collected = $245.

Percentage of amount she hopes to collect = 70%.

Now, to get the total money Rachael plan to collect:

$70\%\ of\ x=245$

$\frac{70}{100} \times x=245$

$0.70x=245$

Dividing both sides by 0.70 we get:

$x=\$345.$

Therefore, the money Rachael plan to collect for the shelter is $345.

Answer:

Step-by-step explanation:

Your question doesn't match the picture. OCR is often inaccurate!—not that it matters much in this case. None of the choices is correct.

(20-4)·6² + 2 + 18 = 16·6² + 2 + 18

= 16·36 + 2 + 18

= 576 + 2 + 18

= 578 + 18

= 596

the original price of a collectible model airplane is $115. The discounted price is $99. What is the percent of discount to the

storchak [24]

Answer:

$99/$115 x 100% = 86.086% of the original price

So 100% - 86.086

= 13.9 = 14%

Or you could just do (115 - 99) x 100 which gets the same answer.

This is a standard deviation contest. You must choose four numbers from the whole numbers 0 to 10 , with repeats allowed. (a) Ch

irina [24]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following instructions :

Choose 4 numbers from the whole numbers 0 - 10

Note : Repetition is allowed

Choose 4 numbers with the smallest possible standard deviation.

The smallest possible value of standard deviation obtainable is 0;

Hence in other to obtain a standard deviation value of 0, then;

The mean squared deviation value must be zero (0)

Σ(X - mean)^2 = 0

To achieve this, the values of X and the mean must be the same.

Hence all 4 numbers (X) must be the same in other to have a mean value which is equal to X

For instance :

If X = 3, 3, 3, 3 (since Repetition is allowed)

Man value = (3+ 3+ 3+ 3) / 4 = 12 / 4 = 3

Σ(3 - 3)² = 0 for all values of x

√Σ(x - mean)² / n = 0 ; if all values of x are the Same

n = Number of observations

A possible list of values is (3,3,3,3)
