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

The school has 6 rows of lockers. Each row has 35 lockers. For the first 5 rows, all of locker are taken. For the last row, 3/5 of the locker are taken , 3/4 of all locker that are taken have decorated name tag. How many locker at school have decorated name tags.
a) 145
b) 141
c) 143
d) 147
The number of locker at school have decorated name tags is 147. Therefore, option D is the correct answer.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, the school has 6 rows of lockers. Each row has 35 lockers.
For the first 5 rows, all of locker are taken.
Number of lockers in 5 rows are 35×5=175
For the last row, 3/5 of the locker are taken is
3/5 ×35 =21
So, the total number of lockers taken = 175+21
= 196
3/4 of all locker that are taken have decorated name tag
Now, 3/4 ×196
= 3×49
= 147
Therefore, option D is the correct answer.

Answer:
ACB=44°
DCE=35°
BCD=101°
Step-by-step explanation:
ACB is a triangle and all triangles are 180 degrees
78+58=136
180-136=44
DCE is also a triangle
85+60=145
180-145=35
a straight line is 180 degrees, we already know what the other two is.
35+44=79
180-79=101

What are Trigonometric Functions?Trigonometric functions are those functions which are the ratio of the sides of a right angled triangle.
Given,
sin² (x) = [1 - cos (2x)] / 2
We have to prove sin ([tex]\frac{x}{2}[/tex]) = ± [tex]\sqrt{\frac{1-cos (x)}{2} }[/tex]
First, we have
sin² (x) = [1 - cos (2x)] / 2
Substituting x/2 in place of x, we get,
sin² (x/2) = [1 - cos (2x/2)] / 2
sin² (x/2) = [1 - cos (x)] / 2
sin² ([tex]\frac{x}{2}[/tex]) = [tex]{\frac{1-cos (x)}{2} }[/tex]
Taking square root on both sides,
sin ([tex]\frac{x}{2}[/tex]) = ± [tex]\sqrt{\frac{1-cos (x)}{2} }[/tex]
Hence it is proved.

If another sample of size 100 is taken, what is the probability that its sample mean will
be greater than 2.56 in?
Answer:
I don't know the answer to this but
Suppose we draw a sample of size n=16 from this population and want to know how likely we are to see a sample average greater than 22, that is P( > 22)? So the probability that the sample mean will be >22 is the probability that Z is > 1.6 We use the Z table to determine this: P( > 22) = P(Z > 1.6) = 0.0548.

Answer:
Area = 240 cm²
Step-by-step explanation:
Area of the shape = area of rectangle + area of triangle
= L*W + ½*bh
L = 18 m
W = 10 m
b = 10 m
h = 30 - 18 = 12 m
Plug in the values
Area of the shape = 18*10 + ½*10*12
= 180 + 60
= 240 cm²
Tarzan is making his mom a card for her birthday. He drew a model of the card before he created it. The model is shown below.
The front of the card is shown. If Tarzan covers the whole front side of the actual card with decorative paper, how much paper would he need? you may use exact answers or round to the nearest hundredth.
Answer:
The area of a triangle uses the equation:
A = ab/2
a = 12
b = 9
A = 12 * 9 / 2
A = 54 inches
54 / 3 = 18
He needs 18 feet of paper
Can someone help me and not be a troll.... I’ll reward points + brainalist
Answer:
The answer is 69.5
Step-by-step explanation:
First u wanna find the area of the rectangle and since it already gives you the the height and width you want to multiply them together 13×4= 52
meanwhile triangle is 5ft tall and the base is 7ft
using the formula to solve for area of a triangle you would multiply height and base and divide by 2
you should end up with 17.5 then u add that to 52 and get 69.5 ♡ Hope this helps.

Answer:
<GHI = 135 degrees
Step-by-step explanation:
(3x + 12) + (x + 4) = 180
4x + 16 = 180
4x + 16 - 16 = 4x
180 - 16 = 164
4x = 164
4x / 4 = x
164 / 4 = 41
x = 41
3 * 41 + 12
3 * 41 = 123
123 + 12 = 135
