Answer:

-3 over 4=x

Step-by-step explanation:

x:1÷4(2x+4)=4

x over 1÷4(2x+4)=4

x over 1×1 over 4(2x+4)=4

x over 4(2x+4)=4

x=4×4(2x+4)

x=32x+64

x-64=32x

-64 over 32= 2x

-3 over 2=2x

-3 over 2÷2=x

-3 over 2 × 1 over 2=x

-3 over 4 =x

i am not sure about my answer tho

Annie's cafe borrows $6100 at 6% for 290 days. Find the total amount that must be repaid after 290 days. (Use a 365 day year.)
Galina-37 [17]
Given:
amount borrowed $6,100
interest rate 6% - assuming annual interest rate
term - 290 days of a 365 day year.

This is a simple interest computation.

Interest = Principal * interest rate * term
Interest = 6,100 * 6% * 290/365
Interest = 290.79

Total payment at the end of the 290 term would be $6,390.79. 

Principal + interest → 6,100 + 290.79 = 6,390.79

timofeeve [1]

Answer:

(a) The average grade point is 2.5.

(b) The relative frequency table is show below.

(c) The mean of the relative frequency distribution is 0.3333.

Step-by-step explanation:

The given data set is

4, 4, 4, 3, 3, 3, 1, 1, 1, 1

(a)

The average grade point is

Average=\frac{\sum x}{n}

Average=\frac{4+4+4+3+3+3+1+1+1+1}{10}

Average=2.5

Therefore the average grade point is 2.5.

(b)

\text{Relative frequency}=\frac{\text{Frequency of number}}{\text{Total frequency}}

The relative frequency table is show below:

x                 f                  Relative frequency

4                3                 \frac{3}{10}=0.3

3                3                 \frac{3}{10}=0.3

1                 4                 \frac{4}{10}=0.4

(c)

Mean of the relative frequency distribution is

Average=\frac{0.3+0.3+0.4}{3}

Average=0.3333

Therefore the mean of the relative frequency distribution is 0.3333.
