Answer:
Step-by-step explanation:
a₄ = a₁ + (4-1)d
4 = -4 + 3d

a₈ = a₄ + (8-4)d = 4 + 4(8/3) = 14⅔
Assume each order is independent. For which type of dinner is the value of its contribution to the appropriate test statistic the greatest?Assume each order is independent. For which type of dinner is the value of its contribution to the appropriate test statistic the greatest?
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.

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
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

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

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
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

m angle R = 120° and m angle S = 100°. Find m angle T. The diagram is not drawn to scale. Quadrilateral R U S T is shown. Side R U is congruent to side R S. Side U T is congruent to Side S T.
A. 20° B. 100° C. 60° D. 40°
Answer:
D.40°
Step-by-step explanation:
Angle U is congruent to angle S because UR = RS and UT=TS. Through that we now know U is also = 100°. A quadrilateral has to equal 360° degrees so 360°- 120° - 100°- 100° = 40° degrees

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.

2. What is the mode of this data set?
Answer:
5 is the mode of the data set.
Step-by-step explanation:
When finding the numbers of a bar graph like this, we count each x and the placement to find the number and amount of times it is shown.
Ex. There is 4 x's above 5. Meaning there are four, 5's. 5, 5, 5, 5.
The mode of a data set, is the number that appears the most often.
So, we can see that the 5 has the most x's, we know that 5 apears the most. Making 5, the mode.
