The product of 3 and the difference of a
number n and 4 is eighteen
Answers
Answer:
n = 10
Step-by-step explanation:
Step 1: Translate word to math
"product" = multiplication
"3" = 3
"difference" = subtraction
"a number n" = n
"4" = 4
"is" means equal
"eighteen" = 18
Step 2: Combine/set up equation
3(n - 4) = 18
Step 3: Solve for n
Distribute 3: 3n - 12 = 18Add 12 to both sides: 3n = 30Divide by 3 on both sides: n = 10Answer:
Equation: 3(n - 4) = 18Solved: n = 10Step-by-step explanation:
To solve:
Apply the distributed property: 3n - 12 = 18Add 12 to each side, so it now looks like this: 3n = 30Divide each side by 3 to cancel out the 3 next to n. It should now look like this: n = 10I hope this helps!

Answers
...................
Answer:
432
Step-by-step explanation:
Original Equation:
3x^2 + 2x + 5
x = -7
3 multiplied by -7 = -21
Equation:
-21^2 + 2x + 5
-21 multiplied to the second power is 441
(two negatives cancel each other out making the number positive)
Equation:
441 + 2x + 5
2 multiplied by -7 is -14
441 + -14 + 5
441 + -14 = 427
427 + 5 = 432

An auto parts manufacturer throws out gaskets with weights that are not within 0.06 pound of the mean weight of the batch. The weights (in pounds) of the gaskets in a batch are 0.58, 0.63, 0.65, 0.53, and 0.61. Which gasket(s) should be thrown out?
Answers
Answer:
0.53 will not chosen
Step-by-step explanation:
Given weights:
0.58, 0.63, 0.65, 0.53, and 0.61.
Computation:
Mean weight X = [0.58+0.63+0.65+0.53+0.61] / 5
Mean weight X = [3] / 5
Mean weight X = 0.60
Acceptable weight = l x-X l < 0.06
l x-0.60 l < 0.06
So solving inequality
0.54 < x < 0.66
So, 0.53 will not chosen.

She spended $7.50 on each book- If the camp leader has 12 campers how much does she spend on the books
Answers
Answer:
$7.50 multiplied by 12 = $90.00
Step-by-step explanation:
Answer:
$90 (assuming 1 book per camper)
Step-by-step explanation:
We are not told the number of books per camper.
If each camper gets 1 book, then since there are 12 campers, then there are 12 books.
12 * $7.50 = $90
(BTW, the word "spended" does not exist. The correct word is "spent.")
At the U.S. Open Tennis Championship a statistician keeps track of every serve that a player hits during the tournament. The statistician reported that the mean serve speed of a particular player was 98 miles per hour (mph) and the standard deviation of the serve speeds was 13 mph. If nothing is known about the shape of the distribution, give an interval that will contain the speeds of at least three-fourths of the player's serves.
a. 124 mph to 150 mph.
b. 85 mph to 111 mph.
c. 59 mph to 137 mph.
d. 72 mph to 124 mph.
Answers
Answer:
d. 72 mph to 124 mph.
Step-by-step explanation:
We solve for this question using the Chebyshev's inequality(x-μ)/σ
For k > 1, 1 - 1/k²
P(x-μ) ≤ kσ≥ 1 - 1/k²
For k = 2
Mean(μ) = 98mph
Standard deviation(σ) = 13mph
P(x-μ) ≤ 2 × 13 mph≥ 1 -1/2²
P(x-μ) ≤ 2 × 13 mph≥ 1 -1/4
P(x-μ) ≤ 26 mph≥ 3/4
According to Chebyshev's theorem,at least 3/4 of the data is 1 standard deviation from the mean
= μ ± σ :μ - σ, μ + σ
The interval is given as: μ - σ, μ + σ
98mph - 26 mph = 72 mph
98 mph + 26 mph = 124 mph
Therefore, the interval = 72mph to 124mph

Chloe's car used 4 gallons to travel 72 miles. How many gallons of gas would she need to travel 270 miles?
Answers
Answer:
15 gallon of gas
Step-by-step explanation:
It is given that,
Chloe's car used 4 gallons to travel 72 miles.
We need to find number of allons of gas that would she need to travel 270 miles.
We firstly find gas required to travel 1 mile.
[tex]1\ \text{mile}=\dfrac{4}{72}\ \text{gallon}[/tex]
For 270 miles,
[tex]270\ \text{mile}=\dfrac{4}{72}\times 270\ \text{gallon}\\\\=15\ \text{gallon of gas}[/tex]
Hence, 15 gallon of gas is needed.

What’s the y-intercept of this graph
Answers
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
Finding the slope:
So first it'll help to find the slope. You could do that by finding two perfect points, which in my case I chose (3,4) and (4,2). Then you tell what the rise over run is....you go down 2 and right 1 to get from (3,4) to (4,2). So the slope would be -2, since we went down it'll become a negative.
Finding the y-intercept:
Then after we found the slope we could easily make an equation and solve it for the y-intercept, but first we'll need to get a point. Let's choose (4,2). So after you got your point you will plug it into the slope formula like this....
[tex]y=mx+b\\\\\\2=-2(4)+b[/tex]
Then we solve it to get....
[tex]2=-2(4)+b\\2=-8+b\\b=10[/tex]
So the y-intercept is 10.

Answers
Answer:
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Find the (a) mean. (b) median. (c) mode, and (d) midrange for the given sample data. An experiment was conducted to determine whether a deficiency of carbon dioxide in the soil affects the phenotype of peas. Listed below are the phenotype codes where 1 = smooth-yellow, 2 = smooth-green, 3 = wrinkled-yellow, and 4= wrinkled-green. Do the results make sense?
Given the phenotype code as 4, 3, 3, 1, 3, 4, 1, 1, 1, 4, 2, 3, 1, 1
a) Mean is the average of the number. It is gotten by taking of the ratio of the variables to the sample size.
Sum of variables = 4+3+3+1+3+4+1+1+1+4+2+3+1+1
Sum of variables = 32
Sample size = 14
Mean = 32/14
Mean = 2.29
The mean phenotype is 2.29
B) median is the value at the middle after rearrangement either in ascendng or descending order.
On rearranging:
1,1,1,1,1,1),2,3,(3,3,3,4,4,4
It can be seen that there are two values at the middle. To get the actual median, we will take the median of the values.
Median = 2+3/2
Median = 5/2
Median = 2.5
Hecke the median phenotype is 2.5
c) The mode is the vale that is occurring the most in the data. It can be seen from the data that 1 is the only value occurring the most (6 times), hence the phenotype mode of the data is 1.
d) Midrange = Highest value + Lowest value/2
Midrange = 1+4/2
Midrange = 5/2
Mid range = 2.5
Hence the midrange of the phenotypic code is 2.5
e) Yes, the measures of center make sense since the data is numerical. Since all our values are numerical and measurable, hence we can conclude that the measure of centres make sense
