Write a linear function f with f(-3)=1 and f(13)=5
Answer:
[tex]y = \frac{1}{4}x +\frac{7}{4}[/tex]
Step-by-step explanation:
Given
[tex]f(-3) = 1[/tex]
[tex]f(13) = 5[/tex]
Required
Determine the linear function
A function is of the form:
[tex]y = f(x)[/tex]
Writing the given parameters in (x,y) format, we have:
[tex]f(-3) = 1[/tex] implies (-3,1)
[tex]f(13) = 5[/tex] implies (13,5)
So, the x and y values are:
(-3,1) and (13,5)
i.e.
[tex](x_1,y_1) = (-3,1)[/tex]
[tex](x_2,y_2) = (13,5)[/tex]
First, we need to determine the slope using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{5 - 1}{13 - -(3)}[/tex]
[tex]m = \frac{4}{13 +3}[/tex]
[tex]m = \frac{4}{16}[/tex]
[tex]m = \frac{1}{4}[/tex]
The equation is calculated as thus:
[tex]y - y_1 = m(x - x_1)[/tex]
Where
[tex](x_1,y_1) = (-3,1)[/tex]
[tex]m = \frac{1}{4}[/tex]
[tex]y - 1 = \frac{1}{4}(x - (-3))[/tex]
[tex]y - 1 = \frac{1}{4}(x +3)[/tex]
[tex]y = \frac{1}{4}(x +3) + 1[/tex]
[tex]y = \frac{1}{4}x +\frac{3}{4} + 1[/tex]
[tex]y = \frac{1}{4}x +\frac{3+4}{4}[/tex]
[tex]y = \frac{1}{4}x +\frac{7}{4}[/tex]
Question 1 of 3 NE A scale drawing of a fishing boat has a scale of 1 cmn to 2 meters. If the length of the fishing boat is 6 cm on the scale drawing, what is the actual length of the fishing boat?
Answer:
12 meters
Step-by-step explanation:
Given
[tex]Scale= 1cm:2m[/tex]
Required
Determine the measurement when the scale reads 6cm
Represent this scale with x;
Such that:
[tex]Scale = 6cm:x[/tex]
Equate
[tex]Scale= 1cm:2m[/tex] and [tex]Scale = 6cm:x[/tex]
[tex]1cm:2m = 6cm:x[/tex]
Express as fraction
[tex]\frac{1cm}{2m} = \frac{6cm}{x}[/tex]
Cross Multiply
[tex]x * 1cm = 6cm * 2m[/tex]
[tex]x * 1 = 6 * 2m[/tex]
[tex]x = 6 * 2m[/tex]
[tex]x = 12m[/tex]

Five companies (A, B, C, D, and E) that make elec- trical relays compete each year to be the sole sup- plier of relays to a major automobile manufacturer. The auto company’s records show that the probabili- ties of choosing a company to be the sole supplier are Supplier chosen: A B C D E Probability: .20 .25 .15 .30 .10 a. Suppose that supplier E goes out of business this year, leaving the remaining four companies to compete with one another. What are the new probabilities of companies A, B, C, and D being chosen as the sole supplier this year? b. Suppose the auto company narrows the choice of suppliers to companies A and C. What is the probability that company A is chosen this year?
Answer:
a
[tex]P(a | e') = 0.22[/tex]
[tex]P(b | e') = 0.28[/tex]
[tex]P(c | e') = 0.33[/tex]
b
[tex]P(a | e' , d' , b') = 0.57 [/tex]
Step-by-step explanation:
From the question we are told that
The probabilities are
Supplier chosen A B C
Probability P(a) = 0.20 P(b) = 0.25 P(c) = 0.15
D E
P(d) = 0.30 P(e) = 0.10
Generally the new probability of companies A being chosen as the sole supplier this year given that supplier E goes out of business is mathematically represented as below according to Bayes theorem
[tex]P(a | e') = \frac{P (a \ and \ e')}{P(e')}[/tex]
[tex]P(a | e') = \frac{P (a)}{P(e')}[/tex]
[tex]P(a | e') = \frac{P (a)}{1- P(e)}[/tex]
=> [tex]P(a | e') = \frac{ 0.20}{1- 0.10}[/tex]
=> [tex]P(a | e') = 0.22[/tex]
Generally the new probability of companies B being chosen as the sole supplier this year given that supplier E goes out of business is mathematically represented as below according to Bayes theorem
[tex]P(b | e') = \frac{P (b \ and \ e')}{P(e')}[/tex]
[tex]P(b | e') = \frac{P (b)}{P(e')}[/tex]
[tex]P(b | e') = \frac{P (b)}{1- P(e)}[/tex]
=> [tex]P(b | e') = \frac{ 0.25}{1- 0.10}[/tex]
=> [tex]P(b | e') = 0.28[/tex]
Generally the new probability of companies C being chosen as the sole supplier this year given that supplier E goes out of business is mathematically represented as below according to Bayes theorem
[tex]P(c | e') = \frac{P (c \ and \ e')}{P(e')}[/tex]
[tex]P(c | e') = \frac{P (c)}{P(e')}[/tex]
[tex]P(c | e') = \frac{P (c)}{1- P(e)}[/tex]
=> [tex]P(c | e') = \frac{ 0.15}{1- 0.10}[/tex]
=> [tex]P(c | e') = 0.17[/tex]
Generally the new probability of companies D being chosen as the sole supplier this year given that supplier E goes out of business is mathematically represented as below according to Bayes theorem
[tex]P(d | e') = \frac{P (d \ and \ e')}{P(e')}[/tex]
[tex]P(d | e') = \frac{P (d)}{P(e')}[/tex]
[tex]P(d | e') = \frac{P (d)}{1- P(e)}[/tex]
=> [tex]P(d | e') = \frac{ 0.30}{1- 0.10}[/tex]
=> [tex]P(c | e') = 0.33[/tex]
Generally the probability that B, D , E are not chosen this year is mathematically represented as
[tex]P(N) = 1 - [P(e) +P(b) + P(d) ][/tex]
=> [tex]P(N) = 1 - [0.10 +0.25 +0.30 ][/tex]
=> [tex]P(N) = 0.35[/tex]
Generally the probability that A is chosen given that E , D , B are rejected this year is mathematically represented as
[tex]P(a | e' , d' , b') = \frac{P(a)}{P(N)}[/tex]
=> [tex]P(a | e' , d' , b') = \frac{0.20 }{0.35 }[/tex]
=> [tex]P(a | e' , d' , b') = 0.57 [/tex]

Answer:
The age of pluto is:
5,560,000,000 years old = 5.56 × 10⁹ years old
x = 5.56
y = power of 9
Step-by-step explanation:
Pluto is 5,560,000,000 years old. Estimate the age of Pluto by writing it in the form of x×10y years, where x and y are single-digit numbers.
We write this in standard form or scientific notation.
5,560,000,000 years old = 5.56 × 10⁹ years old
x = 5.56
y = power of 9
Find the Least Common Denominator of the fractions 5/8 , 1/2 , and 5/6
The Least Common Denominator of the fractions 5/8, 1/2, and 5/6 is 24.
What is least common denominator?The smallest number that can serve as a common denominator for a group of fractions is known as the least common denominator (LCD), also known as the lowest common denominator. The "smallest non-zero common number," a multiple of both numbers, is the least common multiple of two numbers.
How to solve it?Here, the given fractions are 5/8, 1/2, and 5/6.
So, we have to find the least common multiple of 8, 2, and 6 [Since they are the denominators of our given fractions].
8 = 2*2*2
2 = 2*1
6 = 2*3
So LCM of 8, 2, and 6 is 2*2*2*3 = 24
Therefore the Least Common Denominator of the fractions 5/8, 1/2, and 5/6 is 24.

. An independent-measures research study was used to compare two treatment conditions with n=12 participants for each treatment. The first treatment condition had M=55 with a variance of s2=8, and the second treatment condition had M= 52 and s2=4. Look up the appropriate critical value based on your computed degrees of freedom. Do these data indicate a significant difference between the two treatments
Answer:
Decision rule is
Fail to reject the null hypothesis
The conclusion is
There is sufficient evidence that indicate that there is a significant difference between the two treatments
Step-by-step explanation:
From the question we are told that
The sample size is n = 12
The first mean is [tex]M_1 = 55[/tex]
The variance is [tex]s^2_1 = 8[/tex]
The second mean is [tex]M_2 = 52[/tex]
The second variance is [tex]s^2_2 = 4[/tex]
Let the level of significance be [tex]\alpha = 0.05[/tex]
The null hypothesis is [tex]H_o : M_1 = M_2[/tex]
The alternative hypothesis is [tex]H_a : M_1 \ne M_2[/tex]
Generally the test statistics is mathematically
[tex]t = \frac{M_1 - M_2 }{ \sqrt{\frac{s_1^2}{n_1} +\frac{s_2^2}{n_2}} }[/tex]
=> [tex]t = \frac{55 - 52 }{ \sqrt{\frac{8}{12} +\frac{4}{12 }} }[/tex]
=> [tex]t = 1.1619 [/tex]
Generally the degree of freedom is mathematically represented as
[tex]df = 12 -1[/tex]
=> [tex]df = 11 [/tex]
Generally from the t- distriibution table the critical value of [tex]\alpha[/tex] at a degree of freedom of [tex]df = 11 [/tex] is
[tex]t_{0.05 , 11} = 2.20098516[/tex]
Here given that the critical value is greater than the t statistics value the
Decision rule is
Fail to reject the null hypothesis
The conclusion is
There is sufficient evidence that indicate that there is a significant difference between the two treatments

I'm not 100% on #15 but the rest are good.
Step-by-step explanation: When you multiply the percent by the other number that gives you the difference. So then get the original number and either add or subtract the difference from the original number to get your answer. Add if increase Subtract if decrease.
So 7-11 you just have to multiply the percent by the other number.
7. 25*300% or 25*3 = 75 25 + 75 = 100
8. 56*.75 = 42 56-42= 14
9. 12000*.05 = 600 (since it is an increase add 600 to 12000) = 12600
10. 710*.10= 71 (71 is the difference so do this) 710-71= 639
11. 160*.20 = 32 (decrease) 160-32= 128
12. 380*.05=19 (increase) 380+19 = 399
13. 39*.33= 12.87 (decrease)
Discount price = 12.87
Sale price= 39-12.87= 26.13
14. 48*.15 = 7.20 (decrease) 48-7.20= 40.80
15. 3,000*3.25 = 9750 (increase) 9750 + 3000= 12,750
