Answer:
a) 16 cm, b) 37 pieces
Step-by-step explanation:
Part a
Finding the largest divisor of 160, 192 and 240
160 divisors: 1, 2, 4, 5, 8, 10, 16, 32, 40, 80 and 160.
// You can alternatively find them by factor pairs, which are (1, 160), (2, 80), (4, 40), (5, 32), (8, 20) & (10, 16). This way is much more faster. Also, you can simply search them in metanumbers.com
192 divisors: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96 and 192
240 divisors: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120 and 240
The largest divider that they all have in common is 16.
So 16 cm is the largest possible length of each of the shorter pieces of
rope
Part b
Now we have to count how many 16 cm pieces of rope can we get from the large rope pieces, which lengths are 160 cm, 192 cm and 240 cm
160/16 + 192/16 + 240/16 = 10 + 12 + 15 = 37
The answer is 37 pieces

Answer:
f(1) = 2
Step-by-step explanation:
Since f(x) = x^4 + 4 x^3 + 5 x^2 - 4 x - 4
When we evaluate this for x = k = 1, we replace x with the value 1 as shown below:
f(1) = 1^4 + 4 * 1^3 + 5 * 1^2 - 4 * 1 - 4 = 1 + 4 + 5 - 4 - 4 = 10 - 8 = 2

A letter home to the parents of seniors at Westgate High School says, "a simple random sample of 30 Westgate seniors that took the SAT-M test this year produced a mean of 512 and a standard deviation of 95. A confidence interval for the true mean for all WHS seniors is 512.00 ± 47.8." The confidence level for this interval is Group of answer choices
Answer:
It's 99%
Step-by-step explanation:
It just is.
A confidence interval for the true mean for all WHS seniors is 512.00 ± 47.8." The confidence level for this interval is 99%. The correct option is D.
What is the percentage?The percentage is defined as "out of 100." Similar to fractions and decimals, percentages are used in mathematics to represent subsets of a whole. When expressing a sum as a percentage, 100 equal components are regarded to make up the whole.
A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Divide the amount by the total value to get the percentage, then multiply the resulting number by 100.
Since one percent (symbolized as 1%) is equal to one-hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.
Therefore, the correct option is D, 99%.

Can it be concluded that the population mean is greater than 50? Select b. With = 51, what is the value of the test statistic (to 2 decimals)? Can it be concluded that the population mean is greater than 50? Select c. With = 51.8, what is the value of the test statistic (to 2 decimals)? Can it be concluded that the population mean is greater than 50? Select
Answer:
Part a:
The calculate value of Z = 2.946 lies in the critical region so the null hypothesis is rejected and alternate hypothesis is accepted that population mean is greater than 50.
Part b:
The calculate value of Z = 1.17851 does not lie in the critical region so the null hypothesis is accepted that population mean is not greater than 50.
Part c:
The calculate value of Z = 2.1213 lies in the critical region so the null hypothesis is rejected and concluded that population mean is greater than 50.
Step-by-step explanation:
Data as given
H 0: μ ≤ 50 against the claim H a: μ> 50 one tailed test
Z (0.05)= ± 1.645
Sample size n= 50
Using the central limit theorem
Population Standard Deviation= σ=s=6
X= 52.5 , 51 and 51.8
Part a:
Z= x-μ/ s/ √n
Z= 52.5- 50 / 6/ √50
Z= 2.5/0.84853
z= 2.946
The calculate value of Z = 2.946 lies in the critical region so the null hypothesis is rejected and alternate hypothesis is accepted that population mean is greater than 50.
Part b:
Z= x-μ/ s/ √n
Z= 51- 50 / 6/ √50
Z= 1/0.84853
z= 1.17851
The calculate value of Z = 1.17851 does not lie in the critical region so the null hypothesis is accepted that population mean is not greater than 50.
Part c:
Z= x-μ/ s/ √n
Z= 51.8- 50 / 6/ √50
Z= 1.8/0.84853
z= 2.1213
The calculate value of Z = 2.1213 lies in the critical region so the null hypothesis is rejected and concluded that population mean is greater than 50.

Surface area of the triangular prism = 2×Base Area + Perimeter of triangular base×height of prism
Base Area = ½*bh
b = 6 km
h = 5.2 km
Base area = ½*6*5.2 = 15.6 km²
Perimeter of triangular base = 6+6+6 = 18 km
Height of prism = 14 km
Plug in the values into the equation
Surface area of triangular prism = 2×15.6 + 18×14
= 31.2 + 252
= 283.2 km²

This question is incomplete, the complete question is;
An owner of a home in the Midwest installed solar panels to reduce heating costs. After installing the solar panels, he measured the amount of natural gas used y (in cubic feet) to heat the home and outside temperature x (in degree-days, where a day's degree-days are the number of degrees its average temperature falls below 65oF) over a 23-month period.
He then computed the least-squares regression line for predicting y from x and found it to be: y^=80+16x.
How much, on average, does gas used increase for each additional degree-day?
Answer : ______ cubic feet.
(Give your answer as a whole number.)
Answer:
Amount of natural gas used increased by 19 cubic feet.
Step-by-step explanation:
Given the data in the question;
Let the dependent variable y be the amount of natural gas used ( ft³ )
Also let an independent variable x be be the degree days temperature ( in °F)
So the least squares regression equation is;
[tex]y^{bar}[/tex] = 80 + 16x
or
amount_of_natural_gas_used = 80 + 16(degree_days_temperature
Th slope or the standardized regression coefficient of the given regression equation is;
b₁ = 16
the slope coefficient b₁ = 16 is tells us that for each additional one-degree days temperature, an amount of natural gas used increased by 19 cubic feet.
Therefore, amount of natural gas used increased by 19 cubic feet.

How many square feet of outdoor carpet will
we need for this hole?
?
6 ft
2 ft
2 ft
3 ft)
5 ft
3 ft)
12 ft
Please
Answer:48 ft to the second power
Step-by-step explanation:
I just got it right on iready
The area of the outdoor carpet that needed for the hole should be considered as the 48 ft².
Calculation of the area:
Since
we know that
Area of the rectangle = Length (breadth)
here,
L = 12 ft
b = 5 ft
So,
area = 12 × 5
= 60 ft²
Now
The cut off triangle area
area = 1/2 × base × height
= 1/2 × 4 × 3
= 12/2
= 6 ft²
Now
The cut off rectangle area should be
area = Lb
= 3 × 2
= 6 ft²
Now finally
The area of the outdoor carpet should be
= 60 - 6 - 6
= 48 ft²
