Answer:
3/8 of the total distance.
Step-by-step explanation:
After Saturday = 8/8 - 3/8 = 5/8 of distance left.
Sunday = 5/8 x 3/5 = 3/8 distance.

For the first one here is the answer:
Given.
Transitive property of equality- this is becasue the rule is if A=b and B=c then A=c. IN this situation its saying that a is parrelel to b and b is parralel to c therfore a is parrelel to c.
line A and d cross over at 90 degree angles making them perpendicular. -There should be a rule for this and if there is then write that rule down

Consider the population of "last-minute" filers who mail their tax return during the last five days of the income tax period (typically April 10 to April 15).
a. A researcher suggests that a reason individuals wait until the last five days is that on average these individuals receive lower refunds than do early filers. Develop appropriate hypotheses such that rejection of H0 will support the researcherâs contention.
b. For a sample of 400 individuals who filed a tax return between April 10 and 15, the sample mean refund was $910. Based on prior experience a population standard deviation of Ï = $1600 may be assumed. What is the p-value?
c. At α = .05, what is your conclusion?
d. Repeat the preceding hypothesis test using the critical value approach.
Answer and Step-by-step explanation:
Solution:
Develop hypothesis:
H₀ : µ ≥ 1056
H₁ < 1056
Given:
n = 400
ẋ = 910
∂ = 1600
a = 0.05
The sampling distribution of sample means µ and standard deviation ∂ / √n.
Z = ẋ-µ /∂ / √n.
= 910 – 1056 / 1600 /√400.
= - 1.83
Probability: p = p(z< -1.83) = 0.033
At a = 0.05
If p value is smaller than significance level a, then hypothesis is rejected.
P < 0.05 its means H0 rejected.
Hypothesis test using critical value:
The critical value corresponding to probability of 0.05:
Z = -1.645
The rejection region, then contains all values smaller than -1.645.
If value of test statistics is within the rejection region, then null hypothesis rejected.
-1.83 < -1.645
Rejected H

Cos(90-2x) . tan(180+x) + sin^2(360-x)
Answer:
Step-by-step explanation:
Cos(90-2x) . tan(180+x) + sin^2(360-x)
= sin(2x) * tan(x) + sin²(x)
= 2sin(x) cos(x) sin(x)/cos(x) + sin²(x)
= 2sin²(x) + sin²(x)
= 3sin²(x)

determine the rate of change from the two points (3,4)(5,8)
Answer: 2
Step-by-step explanation:
8 - 4 = 4
5 - 3 = 2
4/2 = 2
Answer:
2Step-by-step explanation:
the rate of change or slope from the given two points is rise over run.
(3, 4) (5, 8)
slope = (y2 - y1) / (x2 - x1)
= (8 - 4) / (5 - 3)
= 4 / 2
= 2

Question 4 Part C (3 points): Based on the composite function you created in part A, determine how many trees Carlos can expect to have after 22 days. Click the included image to refer back to Part A as needed.
The composite function is 20d-(80) = 67
A.86 trees in 22 days
B.440 trees in 22 days
C.1340 trees in 22 days
D.1360 trees in 22 days
Answer:
C) 1340 days
Step-by-step explanation:
The composite function you have given is incorrect.
The composite function for this question is:
t(d) = 60d + 20
(as I have proven in a previous question)
Substitute d = 22 into the function:
t(22) = 60(22) + 20
= 1320 + 20
= 1340 days

Answer:
yˆ=2.608x2−115.265x+1568.065
Step-by-step explanation:
I took the test.
The quadratic regression equation best fits the data set is 2.608x² -155.264x + 1568.064 option second is correct.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
Let's suppose the quadratic regression equation best fits the data set:
y = Ax² + Bx + C
From the data set, we can calculate the value of the A, B and C:
A = 2.608
B = -155.264
C = 1568.064
y = 2.608x² -155.264x + 1568.064
Thus, the quadratic regression equation best fits the data set is 2.608x² -155.264x + 1568.064 option second is correct.

Find the degree of this polynomial.
-7d
Hey there!
The degree is the exponent.
Let me explain with examples.
Suppose we have a polynomial 4d.
Its degree is 1 (it's a first degree polynomial)
What is the degree of the polynomial 4d²?
That's right, this is a second-degree polynomial.
And so on...
Let's look at our polynomial.
We have
-7d.
What is the degree of the polynomial?
That's right, 1.
Hence, -7d is a

Solve the formula for the specified variable v=ypu for y
Step-by-step explanation:
