The probability that takes exactly four interviews to find the first applicant with previous experience will be 0.3845.
What is binomial distribution?Frequency distribution of the percentage of successful outcomes that might occur in a certain number of trials with the same chance of success. If X~B(n, p), then the probability is given as
[tex]\rm P(X=x) = \ ^nC_x \times p^x \times (1-p)^{n - x}[/tex]
At a big pharmaceutical company, historically, just 35% of applicants for an internship in statistical programming had prior computer software experience. Assume that candidates are chosen at random and questioned one at a time.
p = 0.35
Then the probability is given as,
P = ⁴C₁ x (0.35)¹ x (1 - 0.35)³
P = 0.3845
The probability that takes exactly four interviews to find the first applicant with previous experience will be 0.3845.

What is the mean, median, mode, and range of 10,14,15,15,16,22,22,22,24,24,27,31,32,37,40,44.
Answer:
mean 16.75
median 15.5
mode 13
range 16
Answer:
25.5 is the median, 22 is the mode, 24.7 is the mean and 34 is the range
Step-by-step explanation:
mean is the average, you get this by adding up all the numbers and then dividing the total by the amount of numbers there are.
the median is the number with the middle value, in this case there were 2 medians because the was an even number of numbers so you average the medians
mode is the number the occurs the most out of the whole set. For example in this case all the numbers occurred twice except 22 which occured 3 times
Last is the range which takes the highest number and subtracts it by the lowest number. It's just that simple!

Grayson is playing a game in which the object is to obtain a 0 by adding the points scored during each round.
Round 1 Round 2 Round 3 Round 4 Round 5
4
7
1
-12
Based on the points he scored during the first 4 rounds, what score does Grayson need on the 5th round?
-24
-11
12
Answer:
0. See explanation below.
Step-by-step explanation:
Grayson is playing a game in which the objective is to obtain a zero, by adding together the points scored in each round.
For rounds 1 to 4,
4 + 7 + 1 + -12 = 12 - 12 = 0
The summation of points in the first four rounds already results to a zero.
Let us see if the addition of any of the three options for round 5 will still result in a zero!
0 + -24 = -24
0 + -11 = -11
0 + 12 = 12
So all the options here are wrong. The only option that would have been correct is 0.
Since 4 + 7 + 1 + -12 + 0 = 0
Maybe the complete question has 0 as the fourth option. Use that.

A bake sale committee wants to raise $175 for a donation to a local charity. They set aside $14 of their profit at the end of each day. How many days will it take them to raise enough money for the whole donation?
Answer:
Number of days= 12.5
Step-by-step explanation:
Giving the following information:
A bake sale committee wants to raise $175 for a donation to a local charity. They set aside $14 of their profit at the end of each day.
To calculate the number of days required to raise $175, we need to use the following formula:
Number of days= total amount / profit per day
Number of days= 175/14
Number of days= 12.5

Over what interval does this function remain constant? Do not use any spaces in your interval.
Answer:
We conclude that the function remains constant over the interval [0, 2].
Step-by-step explanation:
We know that if x increases from left to right and y remains constant, the function remains constant over a certain interval.
From the given graph below, it is clear that from x = 0 to x = 2 the value of y does not change.
In other words, the value of y remains constant from x = 0 to x = 2.
i.e.
at x = 0, y = 5
at x = 1, y = 5
at x = 2, y = 5
Therefore, we conclude that the function remains constant over the interval [0, 2].
A photographer is 6 feet tall and cast a shadow that is 2 feet long. He is photographing a palm tree with a shadow that is 7 feet long. What is the height of the tree
Answer: The height of the tree is 21 feet.
Step-by-step explanation:
Here we can assume that the angle at which the sun impacts the photographer and the tree to be the same angle.
Then we can think in both cases as triangles rectangles, where the height is a cathetus, and the shadow is the other cathetus.
Then we will have a relationship like:
Tg(angle) = shadow/height
height = shadow/Tg(angle)
Now, because for both triangles we have the same angle, then Tg(angle) will be the same number for both cases, and we can just think of it as constant K
Tg(angle) = K
Then we have the equation:
Height = Shadow/K
We know that the photographer is 6ft tall, and his shadow is 2 ft long, we can replace those two things in the above equation and find the value of k:
6ft = 2ft/K
K = 2ft/6ft = (1/3)
Now we know that the shadow of the tree is 7ft long, then the height will be:
height = 7ft/(1/3) = 7ft*3 = 21ft
The tree is 21 ft tall.

Use this information to work out the total fuel bill for 1 working day.
You must show all your working.
Answer: £1517.04
Step-by-step explanation:
The fuel expenses for the vans will be calculated as:
Vans:
Since the average distance travelled per day is 198km and the average distance travelled per litre is 9km, the van would use:
= 198/9
= 22 litres
Since there are 8 vans, they'll use:
= 22 × 8 = 176 liters
Trucks:
Since the average distance travelled per day is 620km and the average distance travelled per litre is 6.2km, the truck would use:
= 620/6.2
= 100
Since there are 10 trucks, they'll use:
= 100 × 10 = 1000 liters
The amount of liters for both the van and the truck will be:
= 176 liters + 1000 liters
= 1176 liters
The fuel cost will then be:
= 1176 × 1£1.29
= £1517.04
Whoever answers number 1 and 2 gets brainliest!! :)
Answer:
1: Yes they are both equivalent because 48/8 is 6 and 24/4 is 6.
2: They would score 750 points because you divide 150 by 3 and get 50, then you multiply 50 by 15 and get 750!

Eduardo opened a credit card at a department store with an APR of 22.29% compounded semiannually. What is the APY on this credit card? (2 points) a 44.58% b 11.15% c 23.53% d 49.55%
Answer:
The correct option is c. 23.53%.
Step-by-step explanation:
The annual percentage yield (APY) can be calculated using the following formula:
APY = (1 + r / n)^n - 1 .............................. (1)
Where;
APY = Annual percentage yield = ?
r = Annual percentage rate = 22.29%, or 0.2229
n = Number of compounding period per year = Semiannually = 2
Substituting the values into equation (1), we have:
APY = (1 + 0.2229 / 2)^2 - 1
APY = 0.2353211025, or 23.53211025%
Rounding to 2 decimal places, we have:
APY = 23.53%
Therefore, the correct option is c. 23.53%.
