Answer:
x² - 10x + 24
Step-by-step explanation:
(x -4)(x - 6)
To write this in standard form, we need to FOIL the binomials.
FOIL: first – outer – inner – last
F: x • x = x²
O: x • -6 = -6x
I: -4 • x = -4x
L: -4 • -6 = 24
Combine the new terms.
x² - 6x - 4x + 24
Combine like terms.
x² - 10x + 24
This is your polynomial in standard form.
Hope this helps!

Use linear regression to find an equation that would best predict a fair home price based on the
comps given below. Round each variable to 4 decimal places.
Answer:
y = 0.0807x - 3.4286
Step-by-step explanation:
Given the data above :
X :
1400
1700
1500
Y:
108
133
120
Using a linear regression calculator, the regression equation obtained is :
y = 0.0807x - 3.4286
Slope = 0.0807
Intercept = - 3.4286
x = predictor variable
y = predicted variable

You are given the results of measurement of resistors. We are testing the
measurement tool. It will pass the technical control if the mean value will be
in the range [198-202] with standard deviation less than 3 Ohms. Will the tool
pass the technical control?
Answer:
As both the standard deviation and the mean have the desired values, the tool passes the technical control.
Step-by-step explanation:
Mean:
The mean is the sum of all values divided by the number of values.
[tex]M = \frac{199+204+201+197+195+204+200}{7} = 200[/tex]
The mean is in the desired range.
Standard deviation:
The standard deviation is the square root of the sum of the difference squared between each value and the mean, divided by the number of values.
[tex]S = \sqrt{\frac{(199-200)^2+(204-200)^2+(201-200)^2+(197-200)^2+(195-200)^2+(204-200)^2+(200-200)^2}{7}} = 1.18[/tex]
As both the standard deviation and the mean have the desired values, the tool passes the technical control.

A new batching plant has been constructed and of the first 50 batches, three are found to not meet specification. a. Construct a 98% Score confidence interval for the population proportion of batches that do not meet specification for the new batching plant. b. Construct a 98% traditional confidence interval.c. Comment on the difference.
Answer:
The responses to these question can be defined as follows:
Step-by-step explanation:
[tex]x=3 \\\\n=50\\\\\hat{p}=\frac{x}{n}=0.06\\\\\hat{q}=1-\hat{p}=0.94[/tex]
In point a:
[tex]98\%[/tex] confidence interval for population proportion (p):
[tex]c=98\%=0.98\\\\\alpha=1-c=0.02\\\\\frac{\alpha}{2}=\frac{0.02}{2}=0.01\\\\z_{\frac{\alpha}{2}}=2.326\\\\[/tex]
For point b:
[tex]98\% \ confidence\ interval =\hat{p} \pm z_{\frac{\alpha}{2}} \sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\\\\[/tex]
[tex]=0.06 \pm 2.326 \sqrt{\frac{0.06\times 0.94}{50}}\\\\ =0.06 \pm 2.326 (0.0336)\\\\=0.06 \pm 0.078\\\\98\% \ CI =(-0.018, 0.138)[/tex]
For point c:

4 Zebras
Step-by-step explanation:
I can only see that she have 5 elephants, possibly more, however it's cut off. If that's true. Then:
If she has 5 elephants (which is currently what she has the most of) and 2 zebras. She needs 4 more zebras. Then she will have 6 zebras. More then any other animal.
Answer:
assuming the elephant has the most dots, as i cant see the full picture, then she needs to collect 4 more because she has 2 already.
Step-by-step explanation:
The elephant has 5 dots
the zebra has 2 dots

What is the average rate of change of function gover the interval [-4,3]?
ОА. -7/2
OB. 1/2
OC. -1/2
OD. 2
Answer:
Option B
Step-by-step explanation:
Average rate of change of a function 'f' in the interval x = a and x = b is given by,
Average rate of change of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
Given function is,
g(x) = [tex]\frac{5}{x-1}+2[/tex]
We have to calculate the rate of change in the interval [-4, 3],
Average rate of change = [tex]\frac{g(3)-g(-4)}{3-(-4)}[/tex]
g(3) = [tex]\frac{5}{3-1}+1[/tex]
= 2.5 + 1
= 3.5
g(-4) = [tex]\frac{5}{-4-1}+1[/tex]
= -1 + 1
= 0
Average rate of change = [tex]\frac{3.5-0}{3+4}[/tex]
= [tex]\frac{3.5}{7}[/tex]
= [tex]\frac{1}{2}[/tex]
Therefore, Option B will be the answer.

A random sample of 340 electronic components manufactured by a certain process are tested, and 30 are found to be defective. A device will be manufactured in which two of the components will be connected in series. The components function independently, and the device will function only if both components function. Let q be the probability that a device functions. Find a 95% confidence interval for q. Round the answers to three decimal places. The 95% confidence interval for q is (
Answer:
95% of the confidence interval for q is
(0.05809 , 0.1183)
Step-by-step explanation:
Step:1
Given that the random sample of 340 electronic components manufactured by a certain process is tested, and 30 are found to be defective.
sample proportion
[tex]q^{-} = \frac{x}{n} = \frac{30}{340} = 0.0882[/tex]
Step:2
95% of the confidence interval is determined by
[tex](q - Z_{0.05} \sqrt{\frac{pq}{n} } , q + Z_{0.05} \sqrt{\frac{pq}{n} } )[/tex]
[tex]((0.0804 -1.96 \sqrt{\frac{0.0804 X0.9118}{340} } ,0.0804 +1.96 \sqrt{\frac{0.0804 X0.9118}{340})[/tex]
[tex]( 0.0882- 1.96 \sqrt{0.000236} , 0.0882 + 1.96 \sqrt{0.000236} )[/tex]
(0.0882 - 0.03011 , 0.0882+0.03011)
( 0.05809 , 0.1183)
Final answer:-
95% of the confidence interval for q is
(0.05809 , 0.1183)

Answer:
The area of the figure is 36 [tex]in^2[/tex].
Step-by-step explanation:
You can cut the composite shapes into two shapes to make the calculation process easier: a triangle and a rectangle. The area of the triangle is [tex]\frac{1}{2} * 9*2=\frac{1}{2} *18=9[/tex] [tex]in^2[/tex], and the area of the rectangle is 9 * 3 = 27 [tex]in^2[/tex], so the area of the composite shape is 27 + 9 = 36 [tex]in^2[/tex].
Answer:
36in²
Step-by-step explanation:
In order to find the area of a composite shape, we must split the shape up into two regular shapes.
Thus, area of composite shape = area of triangle + area of rectangle
The area of a rectangle can simply be found my multiplying the width by the length
The rectangle shown has a length of 9 in and a width of 3 in
Hence, A = 9 * 3
9 * 3 = 27
Therefore the area of the rectangle is 27in²
The area of a triangle can be calculated by multiplying the base length by the height and then dividing the product by 2
The triangle shown has a given height of 2 in and a base length of 9 in
Thus, [tex]A=\frac{2*9}{2}[/tex]
2 * 9 = 18
18 / 2 = 9
Hence, the area of the triangle is 9 in²
Finally we add the two areas together
9 + 27 = 36
Hence, the area of the composite figure is 36in²
