Answer:
You can use proportions by settling the ratio from the sample equal to the ratio from the population.
Explanation:
For Example is 3 out of 50 phones in a sample are defective, then an estimated 60 out of 1000 phones in a population are defective. this can be found by solving the proportion 3/50=x/1000 where x is the estimated number of defective phones in the population.
Answer:
Proportions which would be equal to the ratio from the sample equal to the ratio from the population.
Step-by-step explanation:
I find that Proportions are the easiest way.
Look at this square. Find the value of a.
Answer:
18
Step-by-step explanation:
A square has 4 sides of equal length.
The perimeter of the square is the sum of the lengths of the sides of the square.
P = perimeter; a = length of 1 side
P = a + a + a + a
P = 4a
We are told the perimeter is 72 yd.
4a = 72 yd
Divide both sides by 4.
a = 72/4 yd
a = 18 yd

A tank was filled with 350 gallons of water. Then a crack developed and 18% of the water leaked out of the tank before it could be repaired. How much water leaked out of the tank?
Answer:
its 63 if i'm wrong sorry
Step-by-step explanation:
but what you do is 350 X 18% to get 63
Answer:
63 gallons
Step-by-step explanation:
Question: What is 18 percent of 350?
Percentage solution with steps:
Step 1: Our output value is 350.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, $350 = 100%.
Step 4: Similarly, x = 18%.
Step 5: This results in a pair of simple equations:
350 = 100%(1).
x = 18% (2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
350/x = 100%/18%
Step 7: Again, the reciprocal of both sides gives
x/350=18/100
⇒ x = 63
Therefore, 18% of 350 is 63.
q + 2.02 = 9.2
What does q equal?
Answer:
7.18
Step-by-step explanation:
remember you can rearrange the equation by doing the SAME THING on BOTH SIDES.
q + 2.02 -2.02=9.2-2.02
simplify and you get:
q=7.18
Answer:
7.18 {final answer}
Step-by-step explanation:
→ q + 2.02 = 9.2
→ q = 9.2 - 2.02
→ [ q = 7.18 ]

Step-by-step explanation:
A student claims that the expression “9 times the sum of a number and 13” is translated to the algebraic expression 9n + 13. Is the student correct? If not, what is the correct expression?
Answer: The student is wrong. The correct algebraic expression is 9(n + 13)
The algebraic expression is represented as follows:
The sum of a number and 13 is represented as follows:
Let
n = the number
Therefore,
The sum of a number and 13 is:
n + 13
9 times the sum of a number and 13” can be translated as follows:
9(n + 13)
Therefore, the student is wrong.

Can someone help me and explain how to do these probability questions?
(for the last one, type out the question for say a, b, c, or d)
a. The probability is 1/100 since there are 10 possible digits (0-9) and you need the last two digits so [tex]\frac{1}{10}*\frac{1}{10}=\frac{1}{100}[/tex].
This is 1%.
b. Let's start by calculating the probability of getting the right digits knowing that they are both even.
We have a total of 5 even digits (0, 2, 4, 6, 8). You need the last two so [tex]\frac{1}{5}*\frac{1}{5} =\frac{1}{25}=\frac{4}{100}[/tex] which is 4%.
Therefore the answer is a) It increases the probability that your choice is correct to 1/25, or 4%, because each digit could be 0, 2, 4, 6 or 8.

find the 5 consecutive odd integers if the sum of the first integer is 7 more than the sum of the last 2
Answer: 15,17,19,21,23
Step-by-step explanation:
You can let the middle number = x, then the numbers are
x-4, x-2, x, x+2, x+4
Plugging it back in to what is given,
x-4+x-2+x = 7+x+2+x+4
3x-6 = 2x + 13
x = 19
The numbers are 15, 17, 19, 21, 23

Step-by-step explanation:
To solve for percentages, simply divide the given group by the total.
i.e.,
188/200 = 94% of grasshoppers have brown bodies at the start, and
12/200 = 6% of grasshoppers have brown bodies at the start
Then, for the end
147/350 = 42% of grasshoppers have brown bodies at the end, and
203/350 = 58% of grasshoppers have black bodies at the end.

Is 36 T-shirts in 3 boxes equivalent to 60 T-shirts in 6 boxes?
Answer:no it is not equivalent
Step-by-step explanation:
36x3=108 so there is 108 shirts in that box
60x6=360 so 360 is in that box
so not equivalent because they have different amounts in the boxes one is more and the other one less
your welcome
Answer:
No
Step-by-step explanation:
Since the unit rates 12 t-shirts/1 box
and 10 t-shirts/1 box are not the same, the rates are not equivalent.
