Answer:
a) -1
Step-by-step explanation:
Slope is also known as the gradient
1. assign a value to x and solve for y:
when x = 2, y = 2
when x = 4, y = 0
2. Next, use the equation of a straight line to find the gradient
y = mx + c
y is the y-coordinate, m is the gradient, x is the x-coordinate, c is the point where the line crosses the y-axis, which is found by equating y to 0 and solving for x
so y = mx + c becomes 2 = m*2 + 4, which then becomes 2 = 2m + 4
2m = -2 (take 4 away from 2)
m = -1

Answer: 54°
because QS bisects ∠PQR
=> m∠PQS = m∠RQS
⇔ x + 24 = 3x - 36
⇔ 2x = 60
⇔ x = 30
with x = 30, we have: m∠PQS = 30 + 24 = 54°
Step-by-step explanation:
52% of all Americans are home owners. If 45 Americans are randomly selected, find the probability that a. Exactly 21 of them are are home owners. b. At most 24 of them are are home owners. c. At least 23 of them are home owners. d. Between 20 and 24 (including 20 and 24) of them are home owners.
Answers
Answer:
0.0918 ; 0.6277 ; 0.6064; 0.5055
Step-by-step explanation:
Given that :
Proportion of home owners : p = 0.52
Number of trials = 45
Using binomial distribution formula :
P(x =x) = nCr * p^x * (1 - p)^(n-x)
A.) probability that exactly 21 are homeowners :
P(x = 21) = 45C21 * 0.52^21 * (1 - 0.52)^(45 - 21)
P(x = 21) = 45C21 * 0.52^21 * 0.48^24
P(x = 21) = 3773655750150 * 0.52^21 * 0.48^24
P(x = 21) = 0.0918
b. At most 24 of them are are home
Using the binomial probability to save computation time.
P(x ≤ 24) = p(0) + p(1) +.... + p(24)
P(x ≤ 24) = 0.6277
C.) At least 23 of them are home owners.
P(x ≥ 23) = p(23) + p(24) +... + p(45)
P(x ≥ 23) = 0.6064
d. Between 20 and 24 (including 20 and 24) of them are home owners.
P(20 ≤ x ≤ 24) = p(20) + p(21) + p(22) + p(23) + p(24)
P(20 ≤ x ≤ 24) = 0.0711 + 0.0918 + 0.1084 + 0.1175 + 0.1167
P(20 ≤ x ≤ 24) = 0.5055

Answers
Answer: 32 days. This is more than a month.
Step-by-step explanation:
First, convert the 30 pound bag into ounces. To do this you just need to multiply 30 by 16. You will get 480 ounces (so one bag has 480 ounces of food in it. Then, just divide that by the ounces eaten by Socks in a day. 480/15 is 32. So one bag of food lasts 32 days. At the most, one month can have 31 days in it so this bag will last for more than a month. Hope this helps!

g Explain the difference between explanatory and response variables. Is it important to distinguish between the two in linear regression
Answers
Answer: See explanation
Step-by-step explanation:
The response variable is the variable that the researcher is interested in. It is what the experiment really focuses on.
An explanatory variable is the variable that is being manipulated by the researcher and it explains the variations that may occur to the response variable.
It should also be noted that it is important to distinguish between the response variable and the explanatory variable in a linear regression.
An insurance company charges Ted E. Bear $1400 per year for insurance on his home. The company has predicted that there is a 10% chance that Ted will make a claim on the policy of $5000. Create a probability distribution and determine what the insurance company can expect to make on this policy, on average?
Answers
Answer:
$900
Step-by-step explanation:
The given parameters are;
The amount Ted pays per year for insurance on his home = $1,400
The value of the insurance policy = $5000
The chance that Ted will make a claim on the policy = 10%
The expected value is given as follows
Incidence Probability(p) Value(v) v × p
A claim is made 0.1 $5,000 - $1,400 = -$3,600 -$360
No claim 0.9 $1,400 $1260
Expected value is $1,260 - $360 = $900
The value the insurance company can be expected to make on average on the policy is $900

Write the equation of the line in slope-intercept form that goes through the points: (2, 4) and (7, -1) *
Answers
Answer:
1. slanting upward because the slope is positive one.
2. A: 3/4 B: 4/-3
3. A: 3 B: y=3x-10
1. (-2-7)/(-4-5) = -9/-9 = 1
2. A: (7-4)/(7-3) = 3/4
B: (8-0)/(-6-0) = 8/-6 = 4/-3
3. find the slope first so (4-1)/(2-1)= 3/1. then you plug in point C to find the y intercept so y=mx+b would be 2=3(4)+b which makes it so b is -10. the new equation would be y=3x-10

h(y) 0.325 0.27 0.18
E (x+Y) = E(X) +E(Y)
E(X)= ∑ xi g(x)i
= ( 0*0.05) + (1*0.1) + (2* 0.24) + (3*0.3) + (4*0.2)
= 0 + 0.1+ 0.48 + 0.9+0.8
=2.28
E(Y)= ∑yi h(y)
= (0* 0.325) + (1*0.27) + (2*0.18)
= 0 +0.27+ 0.36
= 0.63
E (x+Y) = E(X) +E(Y)
= 2.28 + 0.63
= 2.91
But the equation is 3x+ 10y
E(3x+ 10y)= 3E(x) + 10 E(y)
= 3(2.28) + 10 (0.63)
= 6.84 +6.3
