5.23 Point-slope form: write an equation PPE
A line that includes the point (6, 1) has a slope of 9. What is its equation in point-slope form?
Use the specified point in your equation. Write your answer using integers, proper fractions,
and improper fractions. Simplify all fractions.
Y-
(x-)
Answer: [tex](y-1)=9(x-6)[/tex]
Step-by-step explanation:
If a line is passing through the point (a,b) and has a slope m, then the equation of the line in point-slope form is given by :-
[tex](y-b)=m(x-a)[/tex]
Given: A line that includes the point (6, 1) has a slope of 9.
The equation of line in point-slope form: [tex](y-1)=9(x-6)[/tex]
Hence, the required equation in point slope form: [tex](y-1)=9(x-6)[/tex]
What is the value of y?
Answer:
y = 25
Step-by-step explanation:
Hey There!
The angle labeled x is supplementary to the angle that is equal to 115 meaning that the sum of the two angles will add up to equal 180
so to find x we subtract 115 from 180
180-115=65 so x = 65
Now we can find y
remember the sum of the triangles angles add up to equal 180
so we subtract the given angles(90 and 65) from 180
180-90-65=25
so y = 25
3. Which of the following is a polynomial with roots 4,6, and - 7
Answer: P(x)= x³ - 3 x² - 46 x +168
Step-by-step explanation:
(4,6, -7)
hence the polynomial will be equal to
P(x) = (x-4) (x-6) (x+7)
P(x) = (x-4) (x²+7 x -6 x -42)
P(x) = (x-4) (x²+x -42)
P(x) = x³ + x²-42 x -4 x² -4 x +168
P(x) = x³ - 3 x² - 46 x +168
hence, the required polynomial is P(x) = x³ - 3 x² - 46 x +168

Answer:
(c) 180 cm²
Step-by-step explanation:
Maybe you want the area of the trapezoid. That is given by the formula ...
A = (1/2)(b1 +b2)h
where b1 and b2 are the base lengths, and h is the height.
Here, the top base is marked 16 cm, and the bottom base is shown as 4 cm longer, so is 20 cm.
A = (1/2)(16 cm +20 cm)(10 cm) = 180 cm²
David drove 135 miles in 3 hours
Answer: 45 miles per hour
Step-by-step explanation:
Answer: if you are trying to find the hourly rate it's 45/hr. If your looking for minute rate it's .75/min. If you are looking for seconds rate it's .0125/sec
Step-by-step explanation: divide 135 by 3 for hourly rate. Divide 45 by 60 for minute rate. Divide .75 by 60 to to get seconds rate.

Can someone find the surface area of the composite shape and show work! I’ll give 30pts! Thanks!
Answer:
382 cm²
Step-by-step explanation:
The shape can be decomposed into two rectangular prism or cuboids
✔️Dimension of prism 1 (smaller prism):
L = 10 cm
W = 3 cm
H = 7 - 4 = 3 cm
Surface area of prism 1 = 2(LW + LH + WH)
= 2(10*3 + 10*3 + 3*3)
= 2(69)
Surface area of prism 1 = 138 cm²
✔️Dimension of prism 2 (larger prism):
L = 10 cm
W = 8 cm
H = 4 cm
Surface area of prism = 2(LW + LH + WH)
= 2(10*8 + 10*4 + 8*4)
= 2(152)
Surface area of prism 2 = 304 cm²
✅Surface Area of the composite shape = (Surface area of prism 1 + surface area of prism 2) - (2 × area of the base of prism 1)
= (138 + 304) - (2 × L × W)
= 442 - (2 × 10 × 3)
= 442 - 60
= 382 cm²
A cube has a edge of 8 cm it is cur into two equal parts calculate the ratio of total surface area
Answer:
[tex]Ratio = 3: 2[/tex]
Step-by-step explanation:
Given
Shape: Cube
[tex]L = 8cm[/tex]
The surface area is calculated as:
[tex]Area = 6*L^2[/tex]
[tex]A_1 = 6*8^2[/tex]
[tex]A_1 = 384[/tex]
When it is cut by half; the length is affected; so, it forms a cuboid of the following dimension:
[tex]L = \frac{8}{2} = 4[/tex] --- Length
[tex]W = 8cm[/tex] --- Width
[tex]H = 8cm[/tex] --- Height
The surface area is:
[tex]Area = 2 *(L*W + H * L + W * H)[/tex]
[tex]A_2 = 2 *(4*8 + 8 *4 + 8 * 8)[/tex]
[tex]A_2 = 2 *128[/tex]
[tex]A_2 = 256[/tex]
So, the ratio of surface area is:
[tex]Ratio = A_1 : A_2[/tex]
[tex]Ratio = 384 : 256[/tex]
Divide by 128
[tex]Ratio = 384/128 : 256/128[/tex]
[tex]Ratio = 3: 2[/tex]
A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 419 gram setting. It is believed that the machine is underfilling the bags. A 15 bag sample had a mean of 409 grams with a standard deviation of 22. A level of significance of 0.05 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
Answer:
We reject the null hypothesis, and accept the alternative hypothesis.
So, it means that the machine is under filling the bags
Step-by-step explanation:
Given
Null Hypothesis
[tex]H_0:\mu = 419[/tex] --- works correctly at 419g
Alternate Hypothesis
[tex]H_0:\mu < 419[/tex] --- under fills the bag
[tex]n =15[/tex] --- the sample
[tex]\bar x = 409[/tex] --- the mean
[tex]\sigma = 22[/tex] --- the standard deviation
[tex]\alpha = 0.05[/tex] --- the significance level
Required
What is the decision rule
Since n is less than 30, we make use of t test
[tex]t = \frac{\bar x - \mu}{\sigma/\sqrt n}[/tex]
[tex]t = \frac{409 - 419}{22/\sqrt{15}}[/tex]
[tex]t = \frac{-10}{22/ 3.87}[/tex]
[tex]t = \frac{-10}{5.58}[/tex]
[tex]t = -1.792[/tex]
Calculate df
[tex]df = n-1[/tex]
[tex]df = 15-1[/tex]
[tex]df = 14[/tex]
Calculate the p value from the Student's t-distribution at df = 14 and [tex]t = -1.792[/tex]
[tex]p =0.047[/tex]
Given that: [tex]\alpha = 0.05[/tex]
Since [tex]p < \alpha[/tex]
So, it means that the machine is under filling the bags

Answer:
80in²
Step-by-step explanation:
Hey There!
So the first step of this problem is to find the width of the scale drawing
To do so we need to find the scale factor
To find the scale factor we divide the length of the room by the length of the scale factor
32/8=4
so the scale factor is 4
now to find the width
40/4=10
so the width of the scale drawing is 10 in
now we can find the area given the length and the width
10x8=80in²
so we can conclude that the area of the scale drawing is 80in²
What do you learn about Salesperson age after performing each of the correlation and regression analyses in the prior questions? Although a correlation by itself may not tell you the whole story, it's at least enough to establish causality A correlation analysis is usually enough to tell you what you need to know Even if a correlation is substantial, you don't know for sure until you measure it in a regression model with several other relevant variables If the correlation is negative, the relationship is not likely to be significant
Answer:
The Salesperson age after performing each of the correlation and regression analyses in the prior questions shows that:
Even if a correlation is substantial, you don't know for sure until you measure it in a regression model with several other relevant variables.
Step-by-step explanation:
The simple difference between correlation and causation is that a correlation measures the linear relationship between two variables, while causation is a statistical measure that establishes that one event or variable is the cause of another event or variable. With correlation established, one needs to study the strength of the relationship through a regression analysis before concluding on how one variable affects another variable.
