The probability that less than 20 trees have the disease is; 0.135

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

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.

Answer: The mean is 6, mean also means the constence.

Step-by-step explanation:

6 is able to go into 10,20,30,40. But I maybe wrong, sorry if I am.

Elijah was travelling before his stop than afterwards with speed of 0.5 km/h.

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]

                                               = 3.5 km/h

So, 4-3.5 km/h= 0.5 km/h

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]

==> evaluate exponents

[tex]d=\sqrt{25+36}[/tex]

==> add 25 and 36

[tex]d=\sqrt{61}=7.8[/tex] ( approximately )

The value of the mean of team C and team D will be equal. Then the correct option is B.

The average of a group of numbers is simply defined as the mean. In statistics, the mean is regarded as one of the indicators of central tendency. Arithmetic mean is a term used to describe the average. It's the percentage of the actual number of observations to the sum of the observations.

The dot plots below show the weights of the players of the two teams:

Team C

120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140. Weight (pounds)

Team D

120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140. Weight (pounds)

Then the mean of team C will be

[tex]\mu _c = \dfrac{120 +121 +122 +123 +124 +.....+139 +140}{21}\\\\\mu _c = \dfrac{2730}{21}\\\\\mu _c = 130[/tex]

Then the mean of team D will be

[tex]\mu _d = \dfrac{120 +121 +122 +123 +124 +.....+139 +140}{21}\\\\\mu _d = \dfrac{2730}{21}\\\\\mu _d = 130[/tex]

Then the value of the mean of team C and team D will be equal.

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.
