Sarah will get a 93 on her 8th test.
Step-by-step explanation:
An = A1 + (n-1)d
93 = 65 + (n-1) 4
93 = 65 + 4n - 4
93 -65 + 4 = 4n
32/4 = n

Hong's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Hong $5.80 per pound, and type B coffee costs $4.20 per pound. This month's blend used four times as many pounds of type B coffee as type A, for a total cost of $700.60 . How many pounds of type A coffee were used?
Answer:
31 Pounds
Step-by-step explanation:
Let x = the number of lbs of Type A coffee.
We know that this month's blend used 4 times as many pounds of type B coffee as type A coffee.
Total lbs of coffee = x + 4x
The total cost then is:
($ cost for Type A)(x) + ($ cost for Type B)(3x) = $700.60
$5.80x + $4.20(4x) = $700.60
$5.80x + $16.8x = $700.60
$22.6x = $700.60
x = 31 lbs
Therefore they where 31 pounds of type A coffee used.
Point K is located at (7, 4) in the coordinate plane. Its image is created by the following rule: K' = Ro270°(K).
Which transformation of point K would produce the same result for K as seen in the previous question?
P.S. Pervious question
Point K is located at (7,4) in the coordinate plane. Its image is created by the following rule:
K'=Ro 270°^(k)
What are the coordinates of k'?
A. (4,-7)
B. (4, 7) This is the correct answer.
C. (7, -4)
D. (-7, 4)
After the transformation of 270° clockwise rotation we get K(7, 4)→K'(-4, 7). Therefore, option B is the correct answer.
The given coordinate point is (7, 4).
What is the transformation?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
Rotation of object 270° clockwise direction
The rule of rotating a figure 270 degrees clockwise is (x, y)→(-y, x)
So, K(7, 4) rotated by 270° clockwise we get K'(-4, 7).
After the transformation of 270° clockwise rotation we get K(7, 4)→K'(-4, 7). Therefore, option B is the correct answer.

jamie baked 48 cookies, which is 8 less than twice the number of cookies gina baked what is the equation
So we know that the number x is multiplied by 2 and subtracted by 8 to get the total number of cookies that Gina baked. Lets set up this equation.
48 = 2x - 8
The 2x is our x multiplied by 2 and the - 8 is the 8 less.
Lets solve:
48 = 2x - 8
Add 8 to both sides to isolate the x variable:
48 + 8 = 2x - 8 + 8
56 = 2x
Now we divide the 2 from the 2x in order to fully isolate the variable:
56 = 2x
28 = x
Lets plug 28 in to double check the answer:
48 = 2(28) - 8
48 = 56 - 8
48 = 48
Yes!

"You are the math teacher for the day. Your students need help understanding slop intercept form. Write a detailed explanation in complete sentences and use the academic vocabulary to explain slope intercept."
Answer:
The slope intercept form is the equation of a straight line that is written as y=mx + b, where m is the slope times the x and b is the point where the line crosses the vertical line y-axis.
Step-by-step explanation:
The table shows the world birth rates y (number of births per thousand people) in x years since 1960.a. Identify an equation that models the birth rate as a function of the number of years since 1960.y=1.1x+50y is equal to 1 point 1 x plus 50y=1.1x+35y is equal to 1 point 1 x plus 35y=−0.3x+35y is equal to negative 0 point 3 x plus 35y=−0.3x+50y is equal to negative 0 point 3 x plus 50Question 2b. Interpret the slope and the y-intercept of the line of fit.The slope of −0.3 means that the birth rate is decreasing by about 30 births per 1000 people every 10 years. The y-intercept of 50 means that in 2010 there will be 50 births per thousand people.The slope of , negative 0 point 3, means that the birth rate is decreasing by about 30 births per 1000 people every 10 years. The , y, -intercept of 50 means that in 2010 there will be 50 births per thousand people.The slope of 1.1 means that the birth rate is increasing by about 11 births per 1000 people every 10 years. The y-intercept of 35 means that in 1960 there were 35 births per thousand people.The slope of , 1 point 1, means that the birth rate is increasing by about 11 births per 1000 people every 10 years. The , y, -intercept of 35 means that in 1960 there were 35 births per thousand people.The slope of 1.1 means that the birth rate is decreasing by about 110 births per 1000 people every 10 years. The y-intercept of 50 means that in 2010 there will be 50 births per thousand people.The slope of , 1 point 1, means that the birth rate is decreasing by about 110 births per 1000 people every 10 years. The , y, -intercept of 50 means that in 2010 there will be 50 births per thousand people.The slope of −0.3 means that the birth rate is decreasing by about 3 births per 1000 people every 10 years. The y-intercept of 35 means that in 1960 there were 35 births per thousand people.
Using technology, the least square regression line equation which models the data is : y = -0.3x + 35.
b.) The slope of −0.3 means that the birth rate is decreasing by about 3 births per 1000 people every 10 years. The y-intercept of 35 means that in 1960 there were 35 births per thousand people.
Given the data :
X : __ 0 ___ 10 ____ 20 ___ 30 ___ 40 ___ 50Y:__35.4 __33.6 ___28.3 __27.0 __22.4 _ 20.0Using either a linear regression calculator or excel :
y = -0.3x + 35 Slope, b = - 0.3 Intercept, c = 35The value of the slope, gives the rate of change in y per unit increase in x.
Hence, the slope value of - 0.3 means that birth rate is decreasing by about 30 births per 1000 people.The intercept is the value of y when x = 0 ; This means that the number of births in 1960(beginning of the data collection), there were 35 births per thousand people.

Consider a sample of 52 football games where 32 of them were won by the home team use a 0.01 significance level to test the claim that the probability that the home team wins is greater than one half
According to the information given, it is found that:
The hypothesis tested are:C. [tex]H_0: p = 0.5[/tex], [tex]H_1: p > 0.5[/tex]
The test statistic is z = 1.66.The p-value of the test is of 0.0485.The conclusion is:Fail to reject [tex]H_0[/tex], as there is not sufficient evidence to conclude that the probability that the home team wins is greater than one half.
At the null hypothesis, it is tested if home teams win half their games, that is, if the proportion is of 0.5, hence:
[tex]H_0: p = 0.5[/tex]
At the alternative hypothesis, it is tested if home teams win more than half their games, that is, if the proportion is of more than 0.5, hence:
[tex]H_1: p > 0.5[/tex]
The test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which:
[tex]\overline{p}[/tex] is the sample proportion. p is the proportion tested at the null hypothesis. n is the sample size.For this problem, the parameters are:
[tex]p = 0.5, n = 52, \overline{p} = \frac{32}{52} = 0.6154[/tex]
Hence, the value of the test statistic is:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.6154 - 0.5}{\sqrt{\frac{0.5(0.5)}{52}}}[/tex]
[tex]z = 1.66[/tex]
The test statistic is z = 1.66.
The p-value is the probability of finding a sample proportion above 0.6154, which is 1 subtracted by the p-value of z = 1.66.
Looking at the z-table, z = 1.66 has a p-value of 0.9515.1 - 0.9515 = 0.0485.
The p-value of the test is of 0.0485.
Since the p-value is greater than 0.01, the conclusion is:
Fail to reject [tex]H_0[/tex], as there is not sufficient evidence to conclude that the probability that the home team wins is greater than one half.
