Answer:
x = 7
Step-by-step explanation:
Step 1: Add 6 to both sides.
[tex]3x - 6 + 6 = 15 + 6[/tex] [tex]3x = 21[/tex]Step 2: Divide both sides by 3.
[tex]\frac{3x}{3} = \frac{21}{3}[/tex] [tex]x = 7[/tex]Step 3: Plug in the value to see if it's correct.
[tex]3(7) - 6 = 15[/tex] [tex]21 - 6 = 15[/tex] [tex]15 = 15[/tex]Therefore, x = 7.

The woman will land on the east bank of the river at a downstream of 37.5 miles.
What is meant by relative velocity ?Relative velocity of an object in motion is defined as the velocity of the object with respect to another object.
Here,
Width of the river, W = 60 miles
Velocity of the boat in still water, Vb = 2 mph
Velocity of river, Vr = 5 mph
Relative velocity of the boat with respect to river in downstream,
Vbr = Vb + Vr
Vbr = 8 mph
Drift of the boat, d = Vr W/Vbr
d = 5 x 60/8
d = 37.5 miles downstream
Hence,
The woman will land on the east bank of the river at a downstream of 37.5 miles.

If there are 19 questions and each question has 4 answers, what is the probability she will answer at least one question correctly?
Answer:
0.9958
Step-by-step explanation:
P(being correct) = 1/4 = 0.25
Hence, p = 0.25
n = 19
P(x ≥ 1) = p(x = 1) + p(x = 2) +... + p(x = 19)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
However, to save computation time, we could use a calculator :
Using a calculator,
P(x ≥ 1) = 0.99577
P(x ≥ 1) = 0.9958

Step-by-step explanation:
Sherry and Karl both started their hike with a small bottle filled with water. Tia started her hike with a larger that was 1/2 full. At the end of the hike, Sherry and Tia’s bottles were each half filled with water. Karl’s bottle was filled 1/3 filled with water. Who has the most water left? Construct a math argument to support your answer.
Answer:
The person with the most water left is;
Tia
Step-by-step explanation:
The parameters given in the question are;
The volume of water Sherry and Karl both started their hike with = 1 small bottle each
The volume of water Tia started her hike with = 1/2 of a larger bottle of water
The volume of water Sherry had at the end of the hike = 1/2 of the small bottle of water
The volume of water Tia had at the end of the hike = 1/2 of the large bottle of water
The volume of water Karl had at the end of the hike = 1/3 of the small bottle of water
Let 'x' and 'y' represent the sizes of the bottles of water with Sherry and Karl respectively and let 'Z' represent the size of the bottle of water Tia started the hike with, we have;
The volume water with Tia at the end of the hike = 1/2·x
The volume water with Karl at the end of the hike = 1/2·y
The volume water with Tia at the end of the hike = 1/2·Z
Given;
Z > x
Z > y
∴ 1/2·Z > 1/2·x
1/2·Z > 1/3·y
Therefore, Tia with half of the larger bottle of water at the end of the hike, 1/2·Z has the most water left.

A (skewed to the left)
Step-by-step explanation:
28 is a much smaller number (age) than the rest of the data, so it will be a negatively skewed distributio, aka, skewed to the left.
“A left skewed distribution is sometimes called a negatively skewed distribution because it's long tail is on the negative direction on a number line.”
“A distribution skewed to the left is said to be negatively skewed. This kind of distribution has a large number of occurrences in the upper value cells (right side) and few in the lower value cells (left side).”

A table is shaped like a regular hexagon. The length of one side is (7x + 4) in. and the length of another side is (8x − 1) in. Find the length of a side.
The length of a side of the table is
Answer:
39 in.
Step-by-step explanation:
As it's a regular hexagon all sides are congruent.
Therefore
7x + 4 = 8x - 1
4 + 1 = 8x - 7x
x = 5.
So the required length is 7(5) + 4 = 39 in.

18. Miguel paid $9600 rent for his apartment the first year. Every year for
the next 3 years the rent increased 5%.
a. How much rent did he pay in the fourth year?
b. How much rent did he pay altogether in the 4 years?
Answer:
$11,113.20
$41,377.20
Step-by-step explanation:
The equation that would be used to represent the increase in rent every month is :
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
Rent paid in the first year = 9600
Rent paid in the second year = 9600 x (1.05) = 10,080
Rent paid in the third year = 9600 x (1.05)^2 = 10,584
Rent paid in the fourth year = 9600 x (1.05)^3 = 11,113.20
Rent paid in4 years is the sum of the rents paid each year :
9600 + 10,080 + 10,584 + 11,113.20 = $41,377.2

Sam asked some other children which sport they like. They all choose swimming. Now the most children choose swimming. How many children did Sam ask?
Answer:
five or more than five
Step-by-step explanation:
From the chart, we know that,
Number of children who chose soccer = 7 (this was the highest)
Number of children who chose swimming = 3
So for swimming to be chosen the most, it should gave been chosen by more than 7 children, i.e. 8 children or more than 8.
So the difference between 8 children and 3 children is = 8 - 3
= 5
Thus, 5 is the least number of other children to chose swimming.
Therefore, Sam asked at least 5 number of children or more than 5.
