Fred bought 3 shirts and a tie. He remembers each shirt was $25, and the total cost was $85. How much was the tie?
Answer:
The tie is $10
Step-by-step explanation:
3 shirts were bought, so 25*3 is 75. The total cost is $85, you take 85 and subtract 75 from it and you get the cost of the tie, $10.

Suppose a random sample of biweekly snowfalls in the pacific northwest has a sample mean of x¯=22.2 inches, with a sample standard deviation of s=3.5 inches. Since snowfall amounts in this area are generally symmetric and bell-shaped, we can apply the Empirical Rule.
Between what two amounts are approximate 99.7% of the data?
Using the Empirical Rule, it is found that 99.7% of the data will be between 11.7 and 32.7 inches.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.In this problem, considering the mean and the standard deviation of the data-set, the bounds between which 99.7% of the data-set are given by:
22.2 - 3 x 3.5 = 11.7 inches.22.2 + 3 x 3.5 = 32.7 inches.More can be learned about the Empirical Rule at https://brainly.com/question/24537145
#SPJ1
Answer: 11.7 & 32.7
Step-by-step explanation:
Approximately $99.7\%$ of the snowfall amounts are between 1$$ inches and 2$$ inches.
Correct answers:
1: 11.7 2: 32.7
The Empirical Rule states that approximately 99.7% of the data is within 3 standard deviations of the mean. In terms of the sample mean x¯ and sample standard deviation s, that is between x¯−3s and x¯+3s.
The value 3 standard deviations below the mean is
x¯−3s=22.2−3(3.5)=11.7.
The value 3 standard deviations above the mean is
x¯+3s=22.2+3(3.5)=32.7.
So by the Empirical Rule, we can say that approximately 99.7% of the snowfall amounts are between 11.7 and 32.7 inches.

Please help the distance formula
Answer:
7.8
Step-by-step explanation:
distance formula : [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
where the x and y values are derived from the given points
here the given points are (11,3) and (6,9)
assigning variables
(x1,y1) = (11,3) so x1 = 11 and y1 = 3
(x2,y2) = (6,9) so x2 = 6 and y2 = 9
plugging in values into formula
recall formula [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
==> plug in x1 = 11 , y1 = 3 , x2 = 6 and y2 = 9
[tex]d=\sqrt{(6-11)^2+(9-3)^2}[/tex]
==> subtract values in parenthesis
[tex]d=\sqrt{(-5)^2+(6)^2}[/tex]

When 12 is multiplied by a fraction less than one, which of the following is true about the product.
(I don't know what are the answer choices, but I'm sure this should be one of the choices:)
Answer:
The product of 12 multiplied with a fraction less than 1 will be less than 12 itself.
Step-by-step explanation:
This is true because if you multiply 12 by (for example) 1/2, then your answer is going to be 6 since 12x1=12 itself, and 12x0=0. So that's why, if it's less than 1, then the product is going to be less than 12 itself.
Hence, one of the answer choices can be something like: The product will be less than 12 itself-2x-11y=26;3x-y=24 I have to write it in elimination method

30% of Elm trees have a certain disease. If you sample 80 elm trees, what is the probability that less than 20 trees have the disease?
The probability that less than 20 trees have the disease is; 0.135
How to find the Probability?
The formula for binomial probability is;
P(X = x) = ⁿCₓ * pˣ * (1 - p)⁽ⁿ ⁻ ˣ⁾
We are told that 30% of Elm trees have a certain disease. Thus;
p = 30% = 0.3
n = 80
x = 20
Thus, probability that less than 20 trees have the disease is;
P(X < 20) = P(X = 0) + P(X = 1) + P(X = 2) + ....... + P(X = 19)
Using a binomial probability calculator online gives us;
P(X < 20) = 0.135

graph below.
How much faster was Elijah travelling before his stop than afterwards?
Give your answer in km/h.
Elijah was travelling before his stop than afterwards with speed of 0.5 km/h.
What is formula to calculate speed or velocity?To solve for distance use the formula for distance d = vt, or distance equals speed times time. Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour.
Before his stop, the velocity =[tex]\frac{0.4km}{0.1 h}[/tex]
= 4 km/h
After his stop, the velocity =[tex]\frac{2.7km}{2.2 h}[/tex]
