The junior class has 50 students. Twenty-five students take only French, 15 take only Latin, and 10 take both. If a student is c

hosen at random from the class, what is the probability that the student chosen takes neither French nor Latin?
(It says NEITHER)
a. 0
b. 2/5
c. 3/5

I personally think it would be a. 0 but everywhere I look says 2/5

<em>If a "Junior Class" has 50 students in total and 25 take french, 15 take latin, and 10 take both you find the answer be using subtraction and addition.</em>

<em>Problem Solved:</em>
<em>50 - (25 + 15 + 10)</em>
<em>= 50 - 50 </em>
<em>= 0</em>

<em>So, your answer is correct. Since all students take at least one language class (French, Latin, or Both) the probability that the chosen student takes none of those because all students take at least one. Hope this helped!</em>

<u>Answer: a. 0 (neither)</u>

snow_tiger [21]

Answer:

Step-by-step explanation:

Corresponding fuel efficiencies of manufacturer A's car and manufacturer B's car form matched pairs.

The data for the test are the differences between the efficiencies of manufacturer A's car and manufacturer B's car

μd = fuel efficiency of manufacturer A's car minus the​ fuel efficiency of manufacturer B's car.

A B diff

32 28 4

27 22 5

26 27 - 1

26 24 2

25 24 1

29 25 4

31 28 3

25 27 - 2

Sample mean, xd

= (4 + 5 - 1 + 2 + 1 + 4 + 3 - 2)/8 = 2

xd = 2

Standard deviation = √(summation(x - mean)²/n

n = 8

Summation(x - mean)² = (4 - 2)^2 + (5 - 2)^2 + (- 1 - 2)^2 + (2 - 2)^2 + (1 - 2)^2 + (4 - 2)^2 + (3 - 2)^2 + (- 2 - 2)^2 = 44

Standard deviation = √(44/8

sd = 2.35

For the null hypothesis

H0: μd = 0

For the alternative hypothesis

H1: μd ≠ 0

This is a two tailed test and the distribution is a students t. Therefore, degree of freedom, df = n - 1 = 8 - 1 = 7

2) The formula for determining the test statistic is

t = (xd - μd)/(sd/√n)

t = (2 - 0)/(2.35/√8)

t = 2.41

We would determine the probability value by using the t test calculator.

p = 0.047

Since alpha, 0.1 > the p value 0.047, then we would reject the null hypothesis. Therefore, at 1% significance level, we can conclude that there is a significant difference in the mean MPG (miles per gallon) when testing for the fuel efficiency of these two brands of automobiles.

Luis has saved $6. he doubles the amount he saves each week.does this represent an exponential function?complete:
Ilya [14]

Answer:

This 6(2)^{n-1} represent an exponential function, because his savings increase by a constant factor of 2.

Step-by-step explanation:

It is given that,

Luis has saved $6 and he doubles the amount each week.

So, the amount saved in the next week = 6×2 = 12

This gives the amount saved in the third week = 12×2 = 24

So, we get the sequence 6, 12, 24, 48,.....

It can be written as, 6×2⁰, 6×2¹, 6×2², 6×2³,.....

So, the sequence in the exponential form 6(2)^{n-1}, where 'n' is a natural number.

Also, 6, 12, 24, 48,.....

The numbers are increasing by the factor = \frac{12}{6}=\frac{24}{12}=....=2

Hence, we get,

This 6(2)^{n-1} represent an exponential function, because his savings increase by a constant factor of 2.
