Step-by-step explanation:
Imagine a researcher posed a null hypothesis that in a certain community, the average energy expenditure should be 2,100 calories per day. He randomly sampled 100 people in that community. After he computed the t value by calculating a two-tailed t-statistic, he found that the probability value was 0.10. Thus, he concluded:
Answer: I fail to reject the Null Hypothesis H₀ and conclude that average energy expenditure is 2100 calories per day.
Step-by-step explanation:
Null Hypothesis H₀ : average energy expenditure is 2100 calories per day
Alt Hypothesis H₁: average energy expenditure is NOT 2100 calories per day
now since
P-value (0.10) > ∝ (0.05),
then he should say;
i fail to reject the Null Hypothesis H₀ and conclude that average energy expenditure is 2100 calories per day.
a fisherman floats 58ft. out from the shore. he notices a bird in the sky directly above the shoreline. if the angle of elevation from the fisherman to the bird is 23 degrees, how far is the fisherman from the bird.
Answer:
63 ft
Step-by-step explanation:
We solve this question using Trigonometric function of Cosine
cos θ = Adjacent/Hypotenuse
From the question:
θ = 23°
Adjacent = The distance of the fisherman from shore = 58 ft
Hypotenuse = The distance of the fisherman from the bird = x ft
Hence:
Cos 23 = 58/x
Cross Multiply
Cos 23 × x = 58
x = 58/Cos 23
x = 63.00890189 ft
Approximately = 63 ft
The distance of the fisherman from the bird is 63 ft

why do planets orbit
Answer:
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

4 cups water for every 1/2 cup soap. How much water would be needed if I have 2/3 cup soap
Answer:
8 cups of water
Step-by-step explanation:
You will need 8 cups of water because if you look closely then notice that 1 + 1 = 2 and 2 + 1 = 3 so 2/8 is 8 cups of water.
Simplify.
(6 - i) + (5 – 8i)

What is the unit rate for meters per second if a car travels 450 meters in 25 seconds?
Answer:
18m/s
Step-by-step explanation:
Formula = 450 meters in 25 seconds
Average speed = 450m/25s
The unit rate is equivalent to 18m/s.
[Basically, just divide 450 meters by 25 seconds to get 18 meters per second. 18 is the unit rate :) ]
[ Thank you so much for the brainliest!! I appreciate it! ]
State what additional information is required in order to know that the triangles are congruent for the for the reason given
Answer/Step-by-step explanation:
1. Only one side and an included angle is known. To prove that both triangles are congruent by the SAS Congruence Theorem, an additional information such as a corresponding second side (KJ, and HJ) must be given to be equal to each other.
KJ = HJ
2. Additional information such as a second corresponding angle (angles C and W must be known to prove both triangles are congruent by SAS.
<C = <W
3. Additional information needed is a second corresponding angles must be known to prove the AAS.
4. Additional information needed is the corresponding angles, R and L, which should be equal to prove the ASA.
<R = L
5. Additional information needed: <C = <H
6. Additional information needed: equal hypotenuse lengths of both traingles.

1) Ms. Kitts works at a music store. Last week she sold 6 more than 3 times the number of CDs that she sold this week. Ms. Kitts sold a total of 108 CDs over the 2 weeks. Which system of equations can be used to find L, the number of CDs she sold last week, and t, the number of CDs she sold this week?
Answer:
L = 3t + 6
108 = L + t
Step-by-step explanation:
first, define the variables:
L = # of CDs sold last week
t = # of CDs sold this week
then, let's write what the words of problem tells us in numbers:
"Last week (L), she sold 6 more (+ 6) than 3 times the number of CDs she sold this week (3t)
L = 3t + 6
"She sold a total of 108 CDs over 2 weeks (L + t)
108 = L + t
At a high school the student government is made up of 5 seniors, 4 juniors, 3 sophomores and 2 freshmen. If there are 8 seniors, 9 juniors, 12 sophomores and 7 freshmen running, in how many ways can the student government be selected?
Answer:
32598720Step-by-step explanation:
Combination for the school government requires:
5 out of 8 seniors = 8! / 3!5! = 6*7*8/2*3 = 7*8 = 564 out of 9 juniors = 9! / 4!5! = 6*7*8*9/2*3*4= 7*2*9 = 1263 out of 12 sophomores = 12! / 3!9! = 10*11*12/2*3 = 10*11*2 = 2202 out of 7 fishermen = 7! / 2!5! = 6*7/2 = 21So number of total ways is:

Answer:
a) [tex]h = -\frac{7}{4}[/tex], b) [tex]h = f\,\circ\,g (-5) = \frac{3}{2}[/tex], c) [tex]h = g\,\circ\,f (-2) = \frac{3}{8}[/tex]
Step-by-step explanation:
We proceed to solve each exercise below:
a) [tex]f(-2) +3\cdot g(0)[/tex]
[tex]h = \frac{2\cdot (-2)}{3\cdot (-2)+5}+3\cdot \left(\frac{3}{0+4} \right)[/tex]
[tex]h = \frac{-4}{-6+5} +3\cdot \left(\frac{3}{4} \right)[/tex]
[tex]h = -4+\frac{9}{4}[/tex]
[tex]h = \frac{-16+9}{4}[/tex]
[tex]h = -\frac{7}{4}[/tex]
b) [tex]h = f\,\circ \,g (-5)[/tex]
[tex]h = f\,\circ\,g (x) = \frac{\frac{6}{x+4} }{\frac{9}{x+4}+5 }[/tex]
[tex]h = f\,\circ\,g (x)= \frac{\frac{6}{x+4} }{\frac{9+5\cdot (x+4)}{x+4} }[/tex]
[tex]h = f\,\circ\,g (x) = \frac{6}{29+5\cdot x}[/tex]
[tex]h = f\,\circ\,g (-5) = \frac{6}{29+5\cdot (-5)}[/tex]
[tex]h = f\,\circ\,g (-5) = \frac{3}{2}[/tex]
c) [tex]h = g\,\circ\,f(-2)[/tex]
[tex]h = g\,\circ \, f (x) = \frac{3}{\frac{2\cdot x}{3\cdot x + 5} + 4 }[/tex]
[tex]h = g\,\circ\,f (x) = \frac{3}{\frac{2\cdot x +4\cdot (3\cdot x +5)}{3\cdot x +5 } }[/tex]
[tex]h = g\,\circ \,f (x) = \frac{3\cdot (3\cdot x +5)}{2\cdot x +12\cdot x +20}[/tex]
[tex]h = g\,\circ\,f(x) = \frac{9\cdot x +15}{14\cdot x +20}[/tex]
[tex]h = g\,\circ\,f(-2) = \frac{9\cdot (-2)+15}{14\cdot (-2)+20}[/tex]
[tex]h = g\,\circ\,f (-2) = \frac{-3}{-8}[/tex]
[tex]h = g\,\circ\,f (-2) = \frac{3}{8}[/tex]
