A brownie recipe calls for 1 cup of sugar and 12 cup of flour to make one batch of brownies. To make multiple batches, the equation f=1/2s where f is the number of cups of flour and s is the number of cups of sugar represents the relationship pls i need helpp
what is the question?
Answer:
4/5 or .8
Step-by-step explanation:
You do 4 divided by 5 to get the answer for 1 batch which would equal to 8/10
then you would simplify it to be 4/5.
At the football concessions stand, Tia sold 78 hamburgers and chicken tenders. If she
sold 24 more hamburgers than chicken tenders, how many hamburgers did she sell?
I am going to do this problem with more of an algebraic approach weather or not its the way your teacher wants you to do it like this.
The way to do things algebraically is to just set variables for what you want to find and set up equations to represent each sentence.
As seen there are hamburgers and chickens in this problem. So let's set the numbers of hamburgers to x, and the numbers of chickens to y.
Now write out each sentence using variables.
1.) Tia sold 78 hamburgers and chicken tenders.
x+y=78
2.) If she sold 24 more hamburgers than chicken tenders.
x=y+24
Now that we have the 2 equations, its time to solve.
Since we have x=y+24, we can replace the x in the first equation with the second equation
y+24+y=78
2y+24=78
Now we can subtract 24 from both sides.
2y=54
Simplify
y=27
Solve for x
x=27+24=51

Step-by-step explanation:
Answer: x^4 - 16
Step-by-step explanation:
The following list shows three factors that can either increase or decrease the probability of a Type II error.
The sample size is increased.
The significance level is increased.
The standard error is increased.
Which factors alone will cause the probability of a Type II error to increase?
A
I only
B
II only
C
III only
D
I and II only
E
I, II, and III
Answer:
C) III only
Step-by-step explanation:
An increase in standard error increases variability of the sampling distribution. Due to the increase in variability of the sampling distribution, it is more difficult to detect a true difference, and the probability of a Type II error is increased.
Write the standard equation of the circle with center (-14, -3) that passes through the point (-5,3),
Answer:
[tex](x + 14)^2 + (y + 3)^2 = 117[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle with center [tex](x_0,y_0)[/tex] is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
In which r is the radius.
Center (-14, -3)
This means that [tex]x_0 = -14, y_0 = -3[/tex]
So
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
[tex](x - (-14))^2 + (y - (-3))^2 = r^2[/tex]
[tex](x + 14)^2 + (y + 3)^2 = r^2[/tex]
Passes through the point (-5,3),
This means that when [tex]x = -5, y = 3[/tex]. We use this to find the radius squared. So
[tex](x + 14)^2 + (y + 3)^2 = r^2[/tex]
[tex](-5 + 14)^2 + (3 + 3)^2 = r^2[/tex]
[tex]r^2 = 117[/tex]
So, the equation of the circle is:
[tex](x + 14)^2 + (y + 3)^2 = r^2[/tex]
[tex](x + 14)^2 + (y + 3)^2 = 117[/tex]

Step-by-step explanation:
Alma is estimating the proportion of students in her school district who, in the past month, read at least 1 book. From a random sample of 50 students, she found that 32 students read at least 1 book last month. Assuming all conditions for Inference are met, which of the following defines a 90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month?
A. 32 +1.645,√(32)(18/50)
B. 32+ 1.9620√ √(32)(18/50)
C. 0.64 + 1.282√(0.64 )(0.36)/ 50
D. 0.64 + 1.645√(0.64 )(0.36)/ 50
E. 0.64 + 1.96√(0.64 )(0.36)/ 50
Answer:
D)
[tex](0.64 +1.645 \sqrt{\frac{0.64(0.36)}{50} })[/tex]
90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month
(0.52846 , 0.75166)
Step-by-step explanation:
Step:-1
Given that the random sample size 'n' = 50
The sample proportion
[tex]p^{-} = \frac{32}{50} = 0.64[/tex]
90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month
[tex](p^{-} - Z_{0.90} \sqrt{\frac{p(1-p)}{n}, } , p^{-} +Z_{0.90} \sqrt{\frac{p(1-p)}{n} })[/tex]
Step(ii):-
Level of significance = 0.90
Z₀.₉₀ = 1.645
[tex](0.64 - 1.645 \sqrt{\frac{0.64(1-0.64)}{50}, } , 0.64 +1.645 \sqrt{\frac{0.64(1-0.64)}{50} })[/tex]
[tex](0.64 - 1.645 \sqrt{\frac{0.64(0.36)}{50}, } , 0.64 +1.645 \sqrt{\frac{0.64(0.36)}{50} })[/tex]
(0.64 -1.645(0.06788) , (0.64 + 1.645(0.06788)
(0.52846 , 0.75166)
Final answer:-
90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month
(0.52846 , 0.75166)

[tex]x = 18.5[/tex]
[tex]y = 22.5[/tex]
[tex](b)[/tex]
[tex]x = 10[/tex]
Step-by-step explanation:
Solving (a):
7x - 19 and 3x + 14 are interior angles.
So:
[tex]7x - 19 + 3x +14 = 180[/tex]
Collect like terms
[tex]7x + 3x = 180 - 14 + 19[/tex]
[tex]10x = 185[/tex]
[tex]x = 18.5[/tex]
7x - 19 and 5y - 2 are equal angles --- corresponding angles
So:
[tex]5y - 2 = 7x - 19[/tex]
Make 5y the subject
[tex]5y = 7x - 19+2[/tex]
5y = 7x -17
Make y the subject
[tex]y = \frac{1}{5} (7x - 17)[/tex]
Substitute [tex]x = 18.5[/tex]
[tex]y = \frac{1}{5} (7*18.5 - 17)[/tex]
[tex]y = \frac{1}{5} (112.5)[/tex]
[tex]y = 22.5[/tex]
Solving (b):
The triangle is right-angled.
So:
[tex]5x + 3 + 2x + 17 + 90 = 180[/tex]
Collect Like Terms
[tex]5x + 2x = 180 - 90 - 17-3[/tex]
[tex]7x = 70[/tex]
[tex]x = 10[/tex]

Answer:
X = 120
Y = 60
.......................
Answer:
x=120
y=60
Step-by-step explanation:
So it states that this is an equilateral triangle which means that all of the angles in this triangle or the same
the sum of all the angles is equal to 180 so to find y we divide 180 by 3
180/3=60
y=60
we notice that its supplementary to the angle that measures 60 and supplementary angles add up to equal 180 so to find x we subtract 60 from 180
180-60=120
x=120
