Answer:

2. 3-(-2)-(+5)

⇒3-(-2)-(+5)= 3+2-(+5) = 5-(+5)  =  5-5  = <u>0</u>

3. -(-3-6)-(-4+8)

⇒ -(-9)-(-4+8) = 9-(-4+8)  =  9-4 =5

4. -8-(-3-2)

⇒ -8-5=-13

5. -(-(-5))+7

⇒ -5+7 = 2

6. -(-(-8)+3)

⇒ -(11) = -11

7. -(-6-(-3+1))

⇒6-(-3+1) = 8

8. 1-(14-(11-7))

⇒ 1-(14-4) = 1-10 = -9

Use the formula for computing future value using compound interest to determine the value of an account at the end of 6 years if
nadezda [96]

Answer: the value of the account at the end of 6 years is is $8577

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = 6000

r = 6% = 6/100 = 0.06

n = 4 because it was compounded 4 times in a year.

t = 6 years

Therefore,.

A = 6000(1+0.06/4)^4 × 6

A = 6000(1+0.015)^24

A = 6000(1.015)^24

A = $8577

Please help... need help ASAP due today... which ones are the answers?
andrey2020 [161]

Answer:

Choices 1 and 4 are correct.

Step-by-step explanation:

We first need to find what the slope of the line is. That way, we can find out which possible answers are perpendicular to it:

\frac{4-(-2)}{3-1}=\frac{6}{2}=3

Since we now have the slope, we need the negative reciprocal of it. Remember: if x is the slope, it's negative reciprocal will be -\frac{1}{x}. Therefore, if the line's slope is 3, then we need to find answers with a slope of-\frac{1}{3}.

The first answer is correct, as you have marked. The second answer, while written a little weirdly, does show the slope as 3, which we know as wrong. The third choice is not correct, however. This equation is written in point-slope form, wherey-y_{1}=m(x-x_{1}). The only variable we have to worry about is m, which, in the third choice, is 3. The fourth answer is correct, which sounds weird at first. Let's put that equation into slope-intercept form:

x+3y=9\\3y=9-x\\y=3-\frac{1}{3}x\\y=-\frac{1}{3}x+3

Equations like these can be real sneaky, so it's important not to jump to conclusions with them.

All freshmen, sophomores, juniors, and seniors attended a
Trava [24]

Answer:

The probability is .034375 or 11/320

Step-by-step explanation:

the probability of a senior being chose first is 22 (seniors) divided my total number of students (80) is .275 percent.

multiplied by the probability of a sophomore being chosen 10/80 which equals .125.

multiply those together and you get your probability. 0.034375 or 11/320
