The type of dinner in which the value of its contribution to the appropriate test statistic is the greatest is E) Vegetarian

What is a Test Statistic?

This refers to the derived statistic that is used in the statistical hypothesis testing in an experiment with a sample.

Hence, we can see that from the complete question, there is the tracking of dinner types by the manager and he compares the change in distribution from last year.

He finds that if each order is independent, then the type of dinner which is the value of its contribution to the appropriate test statistic the greatest is vegetarian meals.

2a.

if the middle point is the letter O

answer: LOM is a central angle

central angle means it comes from the center and each part of it is a radius

central angle is the same degree as the degrees of its arc

so it would also be 84 degrees

When Nayeli goes bowling, her scores are normally
distributed with a mean of 135 and a standard deviation of
12. What percentage of the games that Nayeli bowls does
she score less than 128, to the nearest tenth?

Answers

Using the normal distribution, it is found that she scores less than 128 in 28.1% of her games.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

In this problem, the mean and the standard deviation are given, respectively, by [tex]\mu = 135, \sigma = 12[/tex].

The proportion of games in which she scores less than 128 is the p-value of Z when X = 128, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{128 - 135}{12}[/tex]

Z = -0.58

Z = -0.58 has a p-value of 0.281.

She scores less than 128 in 28.1% of her games.

The "given" is a very important keyword in probability. In this case, we're given that the employee takes the bus. That means we soly focus on the "bus" column only. Everything else is irrelevant. This is because we know 100% that whoever we selected takes the bus, and we've shrunk down the population just these employees.

We have 8 males who take the bus out of 12+8 = 20 people who take the bus. Therefore, 8/20 = 0.40 represents the relative frequency of males who take the bus out of all bus commuters. In other words, 40% of the bus riders are male.

Which is an equation of the line that passes through the points (5,2) and (10,-3)?
A. y = x - 3
B. y = x - 8
C. y = -x + 7
D. y = -x + 12

Answers

Answer:

C

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (5, 2 ) and (x₂, y₂ ) = (10, - 3 )

m = [tex]\frac{-3-2}{10-5}[/tex] = [tex]\frac{-5}{5}[/tex] = - 1 , then

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (5, 2 ), then

2 = - 5 + c ⇒ c = 2 + 5 = 7

y = - x + 7 ← equation of line

The answer is C

You get this by first finding the slope between the two points
Y2 - Y1
X2 - X1
It gives you 5/-5 which is -1
So you can narrow it down to options C and D

Now you can just substitute into both equations

2 = -(5) + 7
2 = 2

-3 = -(10) + 7
-3 = -3

Since both coordinates work in C then C is the answer

Tess, who lives in the united states, is on a trip to europe. she is going first to germany, where the currency is the euro (€), and then to switzerland, where the currency is the swiss franc (chf). as she travels from germany to switzerland, she finds that she has the equivalent of $527 remaining in euros, which she wishes to convert to swiss francs. if, at the time of tess’s exchanges, the exchange rate of the us dollar to the euro is 1:0.6957 and the exchange rate of the euro to the swiss franc is 1:1.4755, how many swiss francs does she have? round all currencies to two decimal places. a. 366.63 francs b. 513.39 francs c. 540.96 francs d. 777.59 francs

Answers

answer:

c

explanation:

from dollars to euro

for every us dollar you have 0.6957 euros

so you time that (0.6957) by 527

which is

366.6339 euros

now we need to convert the euros to swiss franc

so we do 366.6339 euros times 1.4755

this will be 540.96831945 chf

rounding to 2 decimal places will be : 540.96

Considering the angle a by cosine rule
11^2 =7 ^2 +15^2 - 2(7)(15)cos(a)
When you do the maths,
Cos(a) =153/210 =0.729
a= cos inverse of 0.729
a=43 degrees


Considering angle b
7^2=15^2 +11^2 -2(11)(15) cos(b)
This will result in cos(b) =297/330=0.9
b= cos inverse of 0.9 = 25.8 degrees


Considering angle c
15^2=7^2 +11^2 - 2(11)(7) cos(c)
Cos(c) will be = -55/154 = -0.357
c= cos inverse of -0.357=110.9

Comparing the angles a,b and c,
C is the largest size in the triangle with an angle of 110.9 degrees
