Answer:

A. Yes

B. No

C. Yes

D. No

Step-by-step explanation:

A and C has an equivalent ratio.

B and D do not.

2:5 x2 = 4:10

Because if we multiply 2 on both the 2 cups of fruit juice and the 5 cups of water we'll get

4:10 which is the ratio of A

If we divide both the 2 cups of fruit juice and the 5 cups of water with 2 we'll get...

2 ÷ 2 = 1

5 ÷ 2 = 2.5

1:2.5 is the ratio for C.

So both C and A are correct

The rest, B and D, are not equivalent.

6) The amount of Jen's monthly phone bill is normally distributed with a mean of $70 and a standard
alexandr402 [8]

Answer:

i)The correct option is  D.) 99.74%

ii) The correct option is B.) 68.26%

Step-by-step explanation:

i) P(10≤X≤70) = P(  (10−40)/10  ≤Z≤   (70−40 )/10 ) =  Pr(−3≤Z≤3)

= 0.9987 - 0.0013 = 0.99734

Therefore the percentage of Jen's monthly phone bills are between $40 and $100 is D.) 99.74%

ii)P(2.1≤X≤3.1) = P(  (2.1 − 2.6) /0.5   ≤ Z  ≤ (3.1−2.6 )/0.5)  =  Pr(−1  ≤Z  ≤1) )

=  0.8413 − 0.1587  =  0.6826

Therefore the percentage of students at college have a GPA between 2.1 a,d 3.1 is B.) 68.26%

Out of 450 applicants for a job, 206 are male and 62 are male and have a graduate degree.
xxMikexx [17]

Answer:

0.3009 is the  probability that the applicant has graduate degree given he is a male.                                                              

Step-by-step explanation:

We are given he following in the question:

M: Applicant is male.

G: Applicant have a graduate degree

Total number of applicants = 450

Number of male applicants = 206

n(M) = 206

Number of applicants that are male and have a graduate degree = 62

n(M\cap G) = 62

\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}

P(M) = \dfrac{206}{450} = 0.4578

P(M\cap G) = \dfrac{n(M\cap G)}{n} = \dfrac{62}{450} = 0.1378

We have to find the probability that the applicant has graduate degree given he is a male.

P(G|M) = \dfrac{P(G\cap M)}{P(M)} = \dfrac{\frac{62}{450}}{\frac{206}{450}} = \dfrac{62}{206} = 0.3009

Thus, 0.3009 is the  probability that the applicant has graduate degree given he is a male.

Please help me I think the answer is 12 cm .
-Dominant- [34]

You can find the value of the hypotenuse if you apply the Pythagorean Theorem, which is show below:


 h²=a²+ b² ⇒ h=√(a² + b²)


 h: hypotenuse (the opposite side of the right angle and the longest side of the triangle).

 a and b: legs (the sides that form the right angle).


 Then, you have:


 h²=a² + b²

 h²=12²+12²

 h=√ ((12)² + (12)²)

 h=12√2


 What is the lenght of the hypotenuse?


 The answer is: The length of the hypotenuse is 12√2
