a university is comparing the grade point averages of biology majors with grade point averages of engineering majors. the university wants to test whether there is a significant difference in the hpa for students in the two majors what are the null and alternative hypotheses that should be used to test this claim
Answer:
H0 : μEng = μBio
H1: μEng ≠ μBio
Step-by-step explanation:
μEng = Engineering average gpa
μBio = Biology average gpa
To test for difference between two sample means , in this case grade point average of biology majors and Engineering major.
Null hypothesis is the initial truth, which is that ; there is no difference in the mean grade point average of both biology and engineering majors
H0 : μEng = μBio
The Alternative hypothesis is the opposite of the null, which is stated has ; there is difference between the average GPA of both Engineering and Biology majors
H1: μEng ≠ μBio

Step-by-step explanation:
1. Delia brushes her teeth 6 hour
each day.
Units of Time
1 week = 7 days
1 hour = 60 minutes
Write and solve an equation to find
how many minutes Delia brushes
her teeth in 1 day. Then use that to
find the number of minutes she
brushes her teeth in 1 week.
Answer:
Answer:
PART A: 28 hours, PART B: 16800 minutes
Step-by-step explanation:
Delia Brushes her teeth = 1/6 hour
PART A
Total Week= 1 week
Total number of days in a week= 7 days
Total number of hours in a day= 24 hours
Total number of hours in a week= 24× 7 hours
Total number of hours in a week= 168 hours
Number of hours that Delia brushes her teeth = × 168 hours
Number of hours that Delia brushes her teeth = 28 hours
Hence, the correct answer is 28 hours
PART B
Total number of days in a week= 7 days
Total number of hours in a week= 168 hours
Total number of minutes in a week= 168 × 60
Total number of hours in a week= 100800 Minutes
Number of minutes that Delia brushes her teeth = × 100800
Number of hours that Delia brushes her teeth = 16800 minutes
Hence, the correct answer is 16800 minutes

Answer:
x = 37.5
Step-by-step explanation:
By Basic Proportionality Theorem:
[tex] \frac{x}{20} = \frac{46 - 16}{16} \\ \\ \frac{x}{20} = \frac{30}{16} \\ \\ x = \frac{20 \times 30}{16} \\ \\ x = \frac{600}{16} \\ \\ x = 37.5[/tex]
Answer:
x=37.5
Step-by-step explanation:
16/20=30/x
cross multiply
16x=600
x=37.5

Answer:
The equation of line p is y = -³/₂x + 3
Step-by-step explanation:
Let's first find the slope of the line. That's equal to Δy/Δx:
(-3 - 6) / (4 - (-2))
= -9 / 6
= -3/2
With that, we can plug it in to the format:
Δy = sΔx, or (y - y1) = s(x - x1):
y - 6 = s(x - (-2))
y - 6 = (-3/2)(x + 2)
y = -3x / 2 - 3 + 6
y = -³/₂x + 3

What's the name of angle C thanks for the help :)
Answer:
Reflex angle
Step-by-step explanation:
Properties of reflex angles:
1). Any angle measuring between 180° and 360°.
2). Other side of the reflex angle is either acute or obtuse angle.
By these properties,
Since, angle C measures more than 180° but less than 360° and opposite angle is an acute angle.
By these properties angle C and angle D are the reflex angles.

A roofing contractor buys 30 bundles of shingles and 4
rolls of roofing paper for $1040.
In a second purchase (at the same prices), the
contractor buys 12 bundles of shingles and 16 rolls of
roofing paper for $2000.
Create and solve a system of equations in order to
determine how much each bundle of shingles (x) and
roll of roofing paper (y) would cost
Answer:
Cost of one bundle of shingles is $20 and cost of one roll of roofing paper is $110.
Step-by-step explanation:
Let the cost of each bundle of shingles = x
And cost of the roofing paper = y
Contractor buys 30 bundles of shingles and 4 rolls of roofing paper for $1040.
30x + 4y = 1040
15x + 2y = 520 -----(1)
In a second purchase contractor buys 12 bundles of shingles and 16 rolls of roofing paper for $2000
12x + 16y = 2000
3x + 4y = 500 --- (2)
Equation (1) multiplied by 2 then subtracted from equation (2)
(3x + 4y) - 2(15x + 2y) = 500 - 1040
(3x - 30x) + (4y - 4y) = -540
-27x = -540
x = 20
From equation (1)
15(20) + 2y = 520
300 + 2y = 520
2y = 220
y = 110
Therefore, cost of one bundle of shingles is $20 and cost of one roll of roofing paper is $110.

A. f(x) = 500(1.057)^x
B. f(x) = 50(1.057)^x
C. f(x) = 500(0.057)^x
D. f(x) = 500(1.57)^x
Answer: A, f(x) = 500(1.057)^x
