The price of a sweater was reduced from $20 to $12 by what percentage was the price of the sweater reduced
If price of a sweater was reduced from $20 to $12 then the percentage was the price of the sweater reduced is 40%.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that the price of a sweater was reduced from $20 to $12.
Original price is 20.
new price is 12.
We have to find the how much percentage was the price of the sweater reduced.
To do this we have to find the difference between prices over the original price and multiply with 100.
Percentage = 20-12/20×100
=8/20×100
=40%
Hence, if price of a sweater was reduced from $20 to $12 then the percentage was the price of the sweater reduced is 40%.

Which line has a slope of 12 and a y-intercept of 2?
Answer: The bottom left picture.
Step-by-step explanation:
The graph shows the linear line crossing through 2 on the y-axis, therefore the y-intercept is 2. The graph also shows the line increasing by going up 1 and over 2, resulting in the slope of the line being 1/2.
If 4 out of 5 People at the picnic are children and there are 24 children at the picnic,many adults are there?
Answer:
6
Step-by-step explanation:
4/5 of the people at the picnic are children. There are 24 children. So 24 is 4/5 of the whole. You ÷4 to find 1/4. This is 6. So you add on the 6 as 1/4 add 4/5 equals the whole number of people there are at the picnic, 5/5. 24 add 6 is 30 so there are 30 le e at the picnic, and 6 adults.

Equivalent ratios are: ()
Note, the ‘()’ is indicating the missing values needing to be filled.
Answer:
60 3 948 3
Step-by-step explanation:
im just diffrent
The required ratio for the burger is 3;6:9 and the ratio for the hot dog is 5:10:15.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Let the missing ratio in Burger be x and the ratio in the Hot dogs be y,
Now,
According to the question,
3 / 5 = x / 10
x = 6
Now,
x / 10 = 9 / y
Substitute the value of x,
6 / 10 = 9 / y
y = 90 / 6
y = 15
Thus, the required ratio for the burger is 3;6:9 and the ratio for the hot dog is 5:10:15.

A company plans to launch a new product. They have traditionally had a 60% success rate with the launch of new products. Market research predicts that a positive test market results is 80% of successfully launched products and a positive market result for 30% of failed product launches. A) If a market test result comes back negative, what is the probability that the product will be successfully launched?
Answer:
The probability that the product will be successfully launched given that the market test result comes back negative is 0.30.
Step-by-step explanation:
Denote the events provided as follows:
S = a product is successfully launched
P = positive test market result
The information provided is:
P (S) = 0.60
P (P | S) = 0.80
P (P | S') = 0.30
Then,
P (P' | S) = 1 - P (P | S) = 1 - 0.80 = 0.20
P (P' | S') = 1 - P (P | S') = 1 - 0.30 = 0.70
Compute the probability of positive test market result as follows:
[tex]P(P)=P(P|S)P(S)+P(P|S')P(S')[/tex]
[tex]=(0.80\times 0.60)+(0.30\times 0.40)\\\\=0.48+0.12\\\\=0.60[/tex]
The probability of positive test market result is 0.60.
Then the probability of negative test market result is:
P (P') = 1 - P (P)
= 1 - 0.60
= 0.40
Compute the probability that the product will be successfully launched given that the market test result comes back negative as follows:
[tex]P(S|P')=\frac{P(P'|S)P(S)}{P(P')}[/tex]
[tex]=\frac{0.20\times 0.60}{0.40}\\\\=0.30[/tex]
Thus, the probability that the product will be successfully launched given that the market test result comes back negative is 0.30.

A manufacturer contracts to supply ball bearings with diameters between 24.60 millimeters and 25.40 millimeters. Product analysis indicates that the ball bearings manufactured have diameters that are normally distributed with a mean of 25.10 millimeters and a standard deviation of 0.20 millimeters. What percentage of ball bearings fail to satisfy the contract specifications?
Answer:
7.3%
Step-by-step explanation:
to get this percentage, we need to use the z-score calculation;
z-score = (x-mean)/SD
mean = 25.10 , SD = 0.2
For diameter 24.60
z-score = (24.6-25.10)/0.2 = -0.5/0.2 = -2.5
For diameter 25.40
z-score = (25.4-25.1)/0.2 = 1.5
So the proportion that will satisfy the specifications will be;
P(-2.5 < z < 1.5)
At this point, we use the standard normal table
P(-2.5 < z < 1.5) = P (z<1.5) - P (Z < -2.5)
From standard normal table;
P(Z < 1.5) = 0.9332
P(z < -2.5) = 0.0062
P(-2.5 < z < 1.5) = 0.9332 - 0.0062 = 0.927
So the proportion that meets specification = 92.7% ( same as 0.927)
Proportion failing to meet specification = 100- 92.7% = 7.3%
Answer: The percentage of ball bearings fail to satisfy the contract specifaction is 7.3 %.
Step-by-step explanation:
First we need to find the standard score of 24.60 and 25.40. Using Standard Score formula.
[tex]\frac{24.60 - 25.10}{.20} =-2.5\\\\\frac{25.4 - 25.10}{.20}=1.5[/tex]
now we need to find the percentages of these Z scores.
-2.5 = .0062 or 00.62%
1.5 = .9332 or 93.32%
now we subtract these two to get the in between percentage.
.9332 - .0062 = .927 or 92.7% is what doesnt fail to satifsy the contract spefications! But to find what does fail to satisfy we have to subtract it by 100% or 1.
1 - .927 = 0.073
7.3%

Write 49 as a product of two primes.
Answer:
49 = 7 x 7
Step-by-step explanation:
if we factor out 49 into its prime factors, we will get
49 = 7 x 7
(this is the answer)
Alternatively, we can recall from our multiplication tables that 49 = 7² = 7 x 7 (which gives the same answer)
Answer:
7² or 7x7
Explanation:
The prime is any number that can only be divided by itself or by one. One is not a cousin. The only prime pair is 2, all the others are unpaireds.
7/7 = 1. 7/1 = 7
7x7 = 49 or
7² = 49.
Other examples;
9 = 3²
25 = 5²

were 102 students at the dance. How many boys and how many girls were
present at the dance? Define two variables and then set up two equations. Solve
using either substitution or elimination.
Answer:
58 girls
44 boys
Step-by-step explanation:
102 divided by 2= 51 have to divide, 14 divided by 2 = 7
51 - 7= 44
51 + 7= 58
58 + 44= 102

g(x) =
Answer:
g(x)= x2
Step-by-step explanation:
g(x)=x2 = f(x)=x2
The graph of g is a vertical stretch by a factor of 2 followed by a translation of 3 units down of the graph of [tex]\rm f(x) = (x-1)^2[/tex] then the function [tex]\rm g(x) = 2(x+4)^2[/tex].
Given :
[tex]f(x) = x^2-2x+1[/tex]The graph of g be a vertical stretch by a factor of 3 and a reflection in the y-axis, followed by a translation 2 units left of the graph of [tex]f(x) = x^2-2x+1[/tex].The following steps can be used to determine the rule for g:
Step 1 - Rewrite the given function f(x).
[tex]\rm f(x) = (x-1)^2[/tex]
Step 2 - Now, the graph is stretched vertically by a factor of 2.
[tex]= 2(x-1)^2[/tex]
Step 3 - Now, reflect the graph about the y-axis.
[tex]=2(-x-1)^2[/tex]
[tex]=2(x+1)^2[/tex]
Step 4 - Now, move to the left by 3 units.
[tex]=2(x+3+1)^2[/tex]
[tex]=2(x+4)^2[/tex]
Therefore, the function [tex]\rm g(x) = 2(x+4)^2[/tex].
