Answer:

0.6

Step-by-step explanation:

-A+(-B) = -A-B

A-(B) = A-B

A+(-B) = A-B

A-(-B) = A+B

-A-(-B) = -A+B = B-A

Therefore:

-1.3-(-1.9) = -1.3+1.9 = 1.9-1.3 = 0.6

Answer:

0.6

Step-by-step explanation:

So the question asks you what is equivalent to -1.3-(-1.9).

I know the answer will be equal to that so let’s solve for the answer

1) distribute the negative sign

-1.3+1.9

Subtract:

1.9-1.3=0.6

So 0.6 is equal to -1.3-(-1.9)

Hope this helps!

Carrie is buying bulk candy for a high school fundraiser. She buys 1000 candy bars for $350. What is the unit cost per candy bar

Darina [25.2K]

B. $0.35
since to find the unit rate of one candy bar, you have to divide $350 by 1000 and you get $0.35
the rate is 350/1000 = 0.35/1

The area of a rectangle is 42 ft squared, and the length of the rectangle is 5 ft more than twice the width. Find the dimensions

stira [4]

Answer:

<h3>Length = 12 ft</h3>

Width = $\frac{7}{2} ft$

Step-by-step explanation:

Given,

Area of rectangle = $42 \: {ft}^{2}$

Width = X

Length = 2x + 5

Now,

$x(2x + 5) = 42$

$2 {x}^{2} + 5x = 42$

$2 {x}^{2} + 5x - 42 = 0$

$2 {x}^{2} + 12x - 7x - 42 = 0$

$2x(x + 6) - 7(x + 6) = 0$

$(2x - 7)(x + 6) = 0$

Either

$2x - 7 = 0$

$2x = 0 + 7$

$2x = 7$

$x = \frac{7}{2}$

Or,

$x + 6 = 0$

$x = 0 - 6$

$x = - 6$

Negative value can't be taken.

So, width = $\frac{7}{2} ft$

Again,

Finding the value of length,

Length = $2x + 5$

$2 \times \frac{7}{2} + 5$

$7 + 5$

$12$

Length = 12 ft

A poll was conducted by a home mortgage company regarding home ownership in the United States. The company polled 1,488 American

____ [38]

If the sample size is 1488 and confidence interval of 99% then the margin of error is 0.03088.

Given sample size of 1488, percentage of those polled own a home be 69% and confidence level be 99%.

We are required to find the approximate margin of error.

Margin of error is the difference between calculated values and real values.

n=1488

p=0.69

Margin of error=z* $\sqrt{p(1-p)/n}$

Z score when confidence level is 99%=2.576.

Margin of error=2.576* $\sqrt{0.69(1-0.69)/1488}$

=2.576* $\sqrt{(0.69*0.31)/1488}$

=2.576* $\sqrt{0.2139/1488}$

=2.576* $\sqrt{0.0001437}$

=2.576*0.01198

=0.03088

Hence if the sample size is 1488 and confidence interval of 99% then the margin of error is 0.03088.
