This is quite an unusual scenario...:/ It all hinges on her weekly earnings. If she were to work 40 hours each week at $10 per hour, then she would have sufficient funds. Even if she were a student working part-time for 30 hours at $8 per hour, she would still accumulate enough.

Let’s determine the actual mean

First, we sum all the values

87+46+90+78+89 = 390

Then, we divide 390 by the count of numbers present.

390/5 = 78

Thus, the mean is 78

Answer:

Step-by-step explanation:

Review the provided matrix

Let matrix B be defined as

It is stated that

By comparing the corresponding elements from both matrices, we derive

Consequently, the needed values are .

Response:

The area of the shaded part is 42.50 cm².

Detailed explanation:

Examine the diagram provided.

The circle has a radius of r = 5 cm.

Dimensions of the rectangle are:

l = 11 cm

b = 11 cm.

Calculate the area of the shaded portion as follows:

Area of the shaded region = Area of rectangle - Area of circle

                                             

Consequently, the shaded area totals 42.50 cm².

The entire question can be found in the attached image.

It's clear that

[volume of a rectangular prism]=L*W*H

<span>Among the options provided, the highest is 100
</span>100>10
100>20
100>60
100>50

V=L*W*H
with V=100 in³ and L=100 in
100 in³=100*W*H----------> W*H=1

<span>Thus, to achieve a maximum length of 100, the multiplication of width and height must equal 1.

The response is
the option A) 100
