3. To make sure the sweater she is knitting will be the right size, Gale knits a sample that is 2 inches long. She knits a second sample that is 14 times as long as the first sample. How many inches long is the second sample?
please help, will mark u brainliest plz plz plz
Hello and good day.
For this question you will use multiplication.
We know that the first same is 2 inches long and the second sample is 14 times long as the first sample.
When some thing says times, it uses multiplication, especially when mentioned in word problems.
So 14 times 2 = 28.
The answer is: The second sample is 28 inches.
28
14x2=28 bro get this right >:P

Which equation describes the line???
Answer:
The answer is D. y-10=2(x-1)
Step-by-step explanation:
[tex]y-y_{1}=m(x-x_{1})[/tex]
First, find the slope from the two points:
m=(10-2)/(1+3)=2
let [tex]y_{1}=10 and x_{1}=1[/tex]
thus, y-10=2(x-1)

If a cone has a height of 16 feet and a volume
of 603.19 cubic feet, find the length of its
diameter.
Answer:
48 feet
Step-by-step explanation:
Use the equation: volume of a cone = 1/3 ×(height × radius ^2)
After finding the radius, multiply it with 2 to get the diameter

As reported in Trends in Television, the proportion of US households who have at least one VCR is 0.592. If 8 households are selected at random, without replacement, from all US households, what is the (approximate) probability that the number having at least one VCR is exactly 4. Be sure to use many decimal places in your calculations (at least 4), but report your answer to three decimal places.
Answer:
0.23825
Step-by-step explanation:
Given :
p = 0.592 ; number of trials, n = 8
x = 4 ; q = 1 - p = 1 - 0.592 = 0.408
Using the binomial probability relation :
P(x = x) = nCx * p^x * q^(n-x)
P(x = 4) = 8C4 * 0.592^4 * 0.408^4
P(x = 4) = 70 * 0.592^4 * 0.408^4
P(x = 4) = 0.23825

Write an equation for the line that is parallel to the given line and that passes through the given point.
Answer:
You just have to put it into Geogebra Classic. It's a great help for this kind of stuff
Use the method of cylidrincal shells to find the volume of the solid generated by rotating the region bounded by the curves y=6x-2x^2 and y=x^2 about the y axis.
Find where the two curves intersect:
y = 6x - 2x ²
y = x ²
6x - 2x ² = x ² → 3x ² - 6x = 3x (x - 2) = 0 → x = 0 and x = 2
Now, for a shell of radius x units away from the axis of revolution, the height of the shell would be the vertical distance between the upper curve and the lower curve. For 0 ≤ x ≤ 2, we have 6x - x ² ≥ x ², so the height of any given shell is (6x - x ²) - x ² = 6x - 2x ².
Then volume of the solid is
[tex]\displaystyle 2\pi \int_0^2 x(6x-2x^2)\,\mathrm dx = 2\pi \left(2x^3-\frac{x^4}2\right)\bigg|_0^2 = \boxed{16\pi}[/tex]
(Need help ASAP, I’m taking a test) A researcher is 95% confident that the interval from 5.09 to 10.13 captures x = the true mean amount of
times models change clothes during a fashion shoot.
Is it plausible that the true mean number of times for all models to change clothes during a fashion shoot may
be 102
No, this is not a plausible value for the population mean, because 10 is within the 95% confidence interval
No, this is not a plausible value for the population mean, because 10 is not within the 9596 confidence
interval
Yes, this is a plausible value for the population mean, because 10 is within the 95% confidence interval
Yes, this is a plausible value for the population mean, because 10 is only a little bit above the upper
boundary of the 95% confidence interval.
Answer:
See below
Step-by-step explanation:
If a proposed value is outside the confidence interval, it is not a plausible value because the interval never catches it. So B is your best choice.
Answer:
C is correct

From the roof of a house the angle of depression of
the top of a tree 20 ft. high was found to be 30°. If
the distance between the house and the tree is
10√2 find the height of the house.
Answer:
GB = CD = 20 ft, GC = BD = 10√3 ft, ∠FAC = 30°, AB = ? Or, AG = 10 ft. hence, the height of the house (AB) = 30 feet is the required answer.
