Open Response Mrs. James buys 5 hat and
glove sets for charity. She has coupons for
$1.50 off the regular price of each set. After
using the coupons, the total cost is $48.75.
Determine the regular price of a hat and
glove set.
Cost ($)
Item
Hat and glove set
р
Scarf
9.99
Answer:
$8.26
Step-by-step explanation:
$48.75= Total
$1.50= Coupon discount
5= Number of Sets bought by Mrs. James
*$48.75-($1.50*5)= $41.28*
41.28= Total after Coupon discount is removed
5= Number of Sets bought by Mrs. James
$41.28/5= $8.256
Round answer to show dollar value
Final Answer
$8.26
The arc length of this circle is 9.42 inches. Determine the length of the radius.
Complete your work in the space provided.
Answer:
Radius = 5.996958 (They probably just want “6”).
Step-by-step explanation:
9.42x4=37.68 (perimeter)
Perimeter=2[tex]\pi[/tex]r
37.68÷2[tex]\pi[/tex]=r
5.996958=r
Data on pull-off force (pounds) for connectors used in an automobile engine application are as follows:
79.6 75.1 78.2 74.1 73.9 75.0 77.6 77.3 73.8 74.6 75.5 74.0 74.7 75.9 72.7 73.8 74.2 78.1 75.4 76.3 75.3 76.2 74.9 78.0 75.1 76.8
If necessary, round all intermediate calculations to four decimal places (e.g. 12.3456).
Required:
a. Calculate a point estimate of the mean pull-off force of all connectors in the population. State which estimator you used and why?
b. Calculate a point estimate of the pull-off force value that separates the weakest 50% of the connectors in the population from the strongest 50%.
c. Calculate point estimates of the population variance and the population standard deviation.
d. Calculate the standard error of the point estimate found in part (a). Interpret the standard error.
e. Calculate a point estimate of the proportion of all connectors.
Answer:
a. A point estimate of the mean pull-force of all connectors in the population is approximately 75.7385
The point estimate for the mean used is the sample mean
b. The point estimate of the pull force that separates the weakest 50% of the connectors from the strongest 50% is 74.3131 N
c. The point estimate of the population variance is approximately 2.8577
The point estimate for the population standard deviation is approximately 1.6905
d. The standard error of the mean is approximately 0.3315
e. The point estimate of a proportion of the connectors are;
(72.7, 0.0385) , (73.8, 0.0769) , (73.9, 0.0385) , (74, 0.0385) , (74.1, 0.0385) ,(74.2, 0.0385), (74.6, 0.0385) , (74.7, 0.0385) , (74.9, 0.0385) , (75.1, 0.0769) , (75.3, 0.0385) , (75.4, 0.0385) , (75.5, 0.0385) , (75.6, 0.0385) , (75.8, 0.0385) , (76.2, 0.0385) , (76.3, 0.0385) , (76.8, 0.0385) , (77.3, 0.0385) , (77.6, 0.0385) , (78, 0.0385) , (78.1, 0.0385) , (78.2, 0.0385) , (79.6, 0.0385)
Step-by-step explanation:
The given data for the pull-force (pounds) for connectors used in an automobile engine are presented as follows;
Pull-force (pounds); 79.6, 75.1, 78.2, 74.1, 73.9, 75.6, 77.6, 77.3, 73.8, 74.6, 75.5, 74.0, 74.7, 75.8, 72.7, 73.8, 74.2, 78.1, 75.4, 76.3, 75.3, 76.2, 74.9, 78.0, 75.1, 76.8
a. A point estimate of the mean pull-force of all connectors in the population is the sample mean given as follows;
[tex]Mean, \ \overline x = \dfrac{\Sigma x_i}{n}[/tex]
[tex]\Sigma x_i[/tex] = The sum of the data = 1966.6
n = The sample size = 26
Therefore, the sample mean, [tex]\overline x[/tex] = 1966.6/26 ≈ 75.7385
The point estimate for the mean is approximately 75.7385
The sample mean was used as the point estimate for the mean because it is simple and representative of the sample
b. The weakest 50% of the connectors are;
72.7, 73.8, 73.8, 73.9, 74, 74.1, 74.2, 74.6, 74.7, 74.9, 75.1, 75.1, 75.3
The sum of forces that separates the weakest 50%, [tex]\Sigma x_{i}_{50 \%}[/tex] = 966.2
The point estimate of the pull force that separates the weakest 50% of the connectors from the strongest 50% = [tex]\Sigma x_{i}_{50 \%}[/tex]/13 = 966.2/13 = 74.3131 N
c. The estimate of the population variance is the sample variance, given as follows;
[tex]s^2 =\dfrac{\sum \left (x_i-\overline x \right )^{2} }{n - 1}}[/tex]
Where;
[tex]{\sum \left (x_i-\overline x \right )^{2} }[/tex] ≈ 71.4415
Therefore;
[tex]s^2 =\dfrac{71.4415 }{25}} \approx 2.8577[/tex]
The point estimate of the population variance, s², is 2.8577
The point estimate for the population standard deviation, σ, is tha sample standard deviation, 's', given as follows;
s = √s² = √2.8577 ≈ 1.6905
The point estimate for the population standard deviation ≈ 1.6905
d. The standard error of the mean is given as follows;
[tex]SE_{\mu_x} = \dfrac{s}{\sqrt{n} }[/tex]
Therefore, we have;
[tex]SE_{\mu_x}[/tex] = 1.6905/√(26) ≈ 0.3315
The standard error indicates the likely hood of the difference between the sample mean and the population mean
e. The point estimate of a proportion of the connectors are;
(Number of sample with a given pull-force value)/(Sample size (26))
Therefore, using Microsoft Excel, we have
(72.7, 0.0385) , (73.8, 0.0769) , (73.9, 0.0385) , (74, 0.0385) , (74.1, 0.0385) ,(74.2, 0.0385), (74.6, 0.0385) , (74.7, 0.0385) , (74.9, 0.0385) , (75.1, 0.0769) , (75.3, 0.0385) , (75.4, 0.0385) , (75.5, 0.0385) , (75.6, 0.0385) , (75.8, 0.0385) , (76.2, 0.0385) , (76.3, 0.0385) , (76.8, 0.0385) , (77.3, 0.0385) , (77.6, 0.0385) , (78, 0.0385) , (78.1, 0.0385) , (78.2, 0.0385) , (79.6, 0.0385)

Answer:
104
Step-by-step explanation:
Hey There!
So essentially what this problem is asking us to do is solve for the missing angle in a triangle
Remember all of the angles in a triangle will add up to 180
so to find the missing angle we subtract the given angles (38 and 38) from 180
180-38-38=104
so we can conclude that angle A equals 104
Hope this helps!
Answer:
104 degrees

In AMNO, the measure of 20=90°, MN = 99 feet, and OM = 52 feet. Find the
measure of M to the nearest degree.
Answer:
x = 58 degrees
Step-by-step explanation:
Using the SOH CAH TOA trigonometry identity
hypotenuse =99
adjacent = 52
angle of elevation = x
cos theta = adj/hyp
cos x = 52/99
x = arccos (52/99)
x = arccos(0.5253)
x = 58 degrees ( to the nearest degree)

Inverse of this
Answer:
The answer is -7, -9, -4, 2, -4, 3, -3, -10, -0
Step-by-step explanation:
If you see them in the number line, the integers on the left are negative and the integers on the right is positive. Therefore, negative numbers are inverses of positive numbers. For example, 1 is the inverse of -1.

A function represented as:
[tex]Function = \{(x_1,y_1),(x_2,y_2)......(x_n,y_n)\}[/tex]
Where:
[tex]Domain=x_1,x_2,....,x_n[/tex]

So:
[tex]G=\{(7, d), (1, a), (8,8), (d, 0)\}[/tex]
[tex]Domain = \{7,1,8,d\}[/tex]
[tex]Range = \{d,a,8,0\}[/tex]
Given the function C(t) = (t - 2)(t + 6) (t - 4):
the coordinates of its C-intercept are
the coordinates of its t-intercepts are
Answer:
c*(t)-((t-2)*(t+6)*(t-4))=0
Step-by-step explanation:
ct - ((t - 2) • (t + 6) • (t - 4)) = 0
ct - (t - 2) • (t + 6) • (t - 4) = 0
3.1 ct-t3+28t-48 is not a perfect cube
ct - t3 + 28t - 48 = 0
Solve ct-t3+28t-48 = 0

An initial investment of $480 is appreciated for 7 years in an account that earns 15%
interest, compounded quarterly. Find the amount of money in the account at the end
of the period.
01) $ 1276.81
O2) $ 1345.58
3) $ 865.58
O4) $ 1296.94
The amount of money in the account at the end of the period would be $1345.58.
What is compound interest?Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
Given is that an initial investment of $480 is appreciated for 7 years in an account that earns 15% interest, compounded quarterly.
We can write the compound interest as -
[tex]$A = P(1 + \frac{r}{n})^{nt}[/tex]
A = 480(1 + 0.15/4)^(4 x 1)
A = 480 + 865.58
A = 1345.58
Therefore, the amount of money in the account at the end of the period would be $1345.58.
