the equations are
option 1. y= -3x+5
option 2. y= -1/3x+5
option 3. y= -3x-5
option 4. y= 1/3x+5
Answer:
option one
Step-by-step explanation:

Find the radius and the diameter to the nearest hundredth when C = 7π yd. Use 3.14 for π.
60 POINTS PLEASE GIVE VALID ANSWER
Answer:
Diameter = 7
Radius = 3.5
Step-by-step explanation:
Hi! Ace here.
So, the formula to find circumference is dπ or 2rπ
So to find the diameter, you do the circumference/π
To find the radius, you'd do the circumference/2π
Plug-in those numbers and there you go!
Hope this helps, let me know if you have any questions.

Which of the following gives the correct negation of the statement "P: x is an even number"?
Question 2 options:
A)
P: ∼x is not an even number.
B)
∼P: x is an even number.
C)
P: ∼x is an even number.
D)
∼P: x is not an even number.
Answer:
The answer is D
Step-by-step explanation:
The negation of a statement has the opposite meaning of the original statement. The negation of a statement is formed by adding the word “not”.
Consider statement P again:
P: x is greater than 9.
The negation of P is:
∼P: x is not greater than 9.
Note that the symbol ∼ is used before a statement to show that it's a negation.
The negation of the statement is x is an odd number or x is not an even number.
What is Conditional Statement?A conditional statement is one that has the syntax "If P then Q," with P and Q denoting sentences. P is referred to as the hypothesis and Q is referred to as the conclusion for this conditional statement. The implication of "If P then Q" is that whenever P is true, Q must also be true.
We have,
P: x is an even number.
As, Negation indicates that the conditional statement's statement is false.
Conditional: P: x is an even number.
Negation: ~P: x is an odd number or x is not an even number.

Answer:
20 plantains and 2480 bananas
Step-by-step explanation (b is bananas + p is plantains):
2500 = b+p
b=124*p
2500=(124*p)+p
2500=125p (divide by 125)
20=p
b=124(20)
b=2480.

Answer:
3.9%
Step-by-step explanation:
Total number of crimes = 408016 + 2050992 + 6971590 + 1160002 = 10590600
percent of robberies = 408016/10590600 = .038526 ≅ 3.9%

A study is done by a community group in two neighboring colleges to determine which college graduates students with more math classes. College A samples 11 graduates. Their average is 4 math classes with a standard deviation of 1.5 math classes. College B samples 9 graduates. Their average is 3.5 math classes with a standard deviation of 1 math class. The community group believes that a student who graduates from college A has taken more math classes, on the average. Test at a 1% significance level.
A. Is this a test of two means or two proportions? Are the populations dependent or independent?
B. Are the populations' standard deviations known or not?
C. Which distribution is to be used?
D. What is random variable?
E. Hypothesis
F. Test is two tailed or one tail
G. Test value=_____.
H. Use P-value method) to reach to the conclusion.
Answer:
A) It is a test of two proportions and the populations are independent of each other
B) The population standard deviations are known : For college A the standard deviation is = 1.5 while for College B population the standard deviation is 1
C) The distribution to be used is 1 distribution
D) The Random variable is the size of the community group
E) Hypothesis : H0 : u1 = u2 . Ha : u1 > u2
F) Test is one tailed
G) Test Value > significance level
F) when; P value > significance level ( 0.01 ) we do accept Null hypothesis
when ; P value < significance level ( 0.01 ) we reject Null hypothesis
Step-by-step explanation:
College A :
sample size = 11
x ( mean ) value = 4
std = 1.5
College B :
sample size = 9
x ( mean value ) = 3.5
std = 1
A) It is a test of two proportions and the populations are independent of each other
