Answer:
a=5
Step-by-step explanation:
first, let's distribute on the left side.
-4(7a+5)=-160
-28a-20=-160 distribution
-28a=-140 adding 20 on both sides
a=5 dividing by -28 on both sides
there's your answer!

Complete Question
The complete question is shown on the first uploaded image
Answer:
a
[tex]P_1 = 0.1333[/tex] , [tex]P_2 = 0.266[/tex], tex]P_3 = 0.200[/tex], [tex]P_4 = 0.333[/tex] , [tex]P_5 = 0.067[/tex]
b
The location with most risk for flood is the location with 5 towns
Step-by-step explanation:
From the question we are told that
The total number of town is n = 15
Generally the missing number of town is mathematically evaluated as
[tex]k = 15 - [2 + 4 + 5 + 1 ][/tex]
=> [tex]k = 3 [/tex]
Generally the probability distribution for frequency is mathematically represented as
[tex]P = \frac{A}{B}[/tex]
Here A is the number of town having these losses (i.e each row under the number of towns having the losses column)
B is the total number of towns
Considering column one
[tex]P_1 = \frac{2}{15}[/tex]
[tex]P_1 = 0.1333[/tex]
Considering column two
[tex]P_2 = \frac{4}{15}[/tex]
[tex]P_2 = 0.266[/tex]
Considering column three
[tex]P_3 = \frac{3}{15}[/tex]
[tex]P_3 = 0.200[/tex]
Considering column four
[tex]P_4 = \frac{5}{15}[/tex]
[tex]P_4 = 0.333[/tex]
Considering column five
[tex]P_5 = \frac{1}{15}[/tex]
[tex]P_5 = 0.067[/tex]
Looking at the table we see that the region with 5 towns receive 3 floods per town and this region of 5 towns has a higher probability distribution for frequency compared to the other region. hence the location with most risk for flood is the location with 5 towns
Find the width of a rectangular wall if the perimeter is 148 feet and the width is two more than seven times the length.
Answer:
Step-by-step explanation:
Perimeter of a rectangular wall P = 2L+2W
L is the length of the wall
W is the width
Given
P = 148feet
If the width is two more than seven times the length, this is represented as
W = 7L+2
Substitute W = 7L+2 into the formula above
P = 2L + 2(7L+2)
P = 2L +14L+4
P == 16L+4
148 = 16L+4
16L = 148-4
16L = 144
L = 144/16
L = 9
To get the width
W = 7L+2
W = 7(9)+2
W = 63+2
W = 65feet
Hence the width of the rectangular wall is 65feet
One United Bank is the largest Black-owned bank in the United States which calculates simple interest using the following equation below.
I=prt
Solve the equation for r, the rate balance.
A. Ir=pt
B. Ipt=r
C. rI=pt
D. ptI=r
Answer:
WHat is it :(
Step-by-step explanation:
Answer:
Easy Question: I/pt=r
Step-by-step explanation:
You take the equation i=prt and you solve it out.
You divide the half "prt" by pt like this: prt/pt
You also do that to the other side "I"
You are left with I/pt=r and there it is!!
Is 4x + 9 equivalent to 2(2x+5) -1?
Answer: Yes!
Step-by-step explanation:
1. So you have: 4x+9 and 2(2x+5)-1
2. Simplify the 2nd expression: 2(2x+5) -1 = 4x + 10 - 1 = 4x+9
4x+9 = 4x+9
Answer:
Yes
Step-by-step explanation:
Set them equal to each other to see. If they are, then you should come out with the answer 0 = 0.
4x + 9 = 2(2x + 5) - 1
4x + 9 = 4x + 10 - 1
0 = 0

Nicole invested $400 in a fund for 6 years and was paid simple interest. The total interest that she received on the investment was $72. As a
percentage, what was the annual interest rate of her investment?
Answer:
83.3333%
Step-by-step explanation:
The accrued amount of an investment is the original principal P plus the accumulated simple interest, I = Prt, therefore we have:
A = P + I = P + (Prt), and finally A = P(1 + rt)

Tell whether the value is a solution of the
- 5 = QS)-1; S = 10
Answer:
S=− [tex]\frac{4}{Q}[/tex]
Step-by-step explanation:
−5=(QS)−1
Swap sides so that all variable terms are on the left hand side.
QS−1=−5
Add 1 to both sides.
QS=−5+1
Add −5 and 1 to get −4.
QS=−4
Divide both sides by Q.
[tex]\frac{QS}{Q}[/tex]=[tex]\frac{-4}{Q}[/tex]
Dividing by Q undoes the multiplication by Q.
S= [tex]\frac{-4}{Q}[/tex]
Divide −4 by Q.
S=− [tex]\frac{4}{Q}[/tex]

A restaurant uses 4 pounds of potatoes for a party of 12 people if they are cooking potatoes for a party of 60 people,what should they do?
Answer:
They should multiply the amount of potatoes by 5. 12 is 1/5 of 60. Therefore, if you need 4 pounds of potatoes for 12 people, then you will need 20 pounds of potatoes for 60 people.
