1.5 x 10^4 = 15,000
9 x 10^3 = 9,000

15,000 - 9,000 = 6,000 <=== or 6 x 10^3

So simply substract......
1.5×10^4-9×10^3

=.6×10^4.......answer

Hello!

280 + 254 = 525

525/2 = 262.5

Now, what's 1/4 of 262.5?

262.5/4 = 65.625

So, she had $65.625 left! I hope you found this helpful! c:

Mrs. Taylor would like to construct a confidence interval for the number of highlighters that are borrowed and not returned in h

Furkat [3]

The confidence interval at a 90% confidence level is (60.9%,75.1%) if in the end of a semester, she loaned 115 highlighters and found that 68% were not returned option (A) is correct.

<h3>What is the margin of error(MOE)?</h3>

It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.

The formula for finding the MOE:

$\rm MOE = Z\times{\sqrt \dfrac{p(1-p)}{n}\\$

Where Z is the z-score at the confidence interval

p is the population proportion

n is the number of samples.

We have p = 68% = 0.68

n = 115

Z score for 90% confidence interval = 1.64

$\rm MOE = 1.64\times{\sqrt \dfrac{0.68(1-0.68)}{115}\\$

MOE = 0.071

So the confidence interval will be:

= (0.68-0.071, 0.68+0.071)

= (0.609, 0.751) or

= (60.9%, 75.1%)

Thus, the confidence interval at a 90% confidence level is (60.9%,75.1%) if in the end of a semester, she loaned 115 highlighters and found that 68% were not returned option (A) is correct.

vodka [1.7K]

Answer:

-1,050

Step-by-step explanation: This is quite simple first we know that 2,100 is negative(-2,100) because it is descending/going down. So now we know that we can divide -2,100 by 2 which sums up to 1,050. But we are going to have to add a negative sign due to the fact that if the two integers you are dividing are opposite signs it would be negative. So if you add a negative sign to 1,050 it would be -1,050. Just to keep in mind that opposites make negative when dividing I will put the integer rules below.

Write an equation in point-slope form of the line that passes through the point (-1,-4) and has a slope of m=-2

Bess [88]

Answer:

y = -2x +6

Step-by-step explanation:

Need to find b, we have 2 points (0,b), (-1,-4) and a slope m = -2

m = (y2 - y1) / (x2 -x1)

-2 = (-4 - b) / (-1 - 0)

Solve for b

-2(-1 - 0) = -4 - b

2 = -4 - b

2 + 4 = b

6 = b

b = 6

Find the total surface area of the triangular pyramid. Each of the faces (sides) has an area of 50.5 square inches.

mylen [45]

By definition we have:
A triangular pyramid (also called tetrahedron) is a polyhedron whose surface is formed by a base that is a triangle and triangular lateral faces that converge in a vertex that is called apex (or apex of the pyramid).
It will be composed, therefore, by 4 faces, the triangular base and three lateral triangles that converge at the vertex.

Thus, the surface area is:
As = 4 * (50.5) = 202 in ^ 2
Answer:
The total surface area of the triangular pyramid is:
202 in ^ 2
