two points on a line L are (5,2) and (7,-4). what is the slope of L

Answer:

Step-by-step explanation:

100%-17.5%= 82.5%

82.5% (divide) 82.5%= 1%

so (1% of the orginal price)=

£264 (divide) 82.5%= £320= original price

The price of the computer is reduced by £56 which is 17.5% of £320.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, The price of a computer is reduced by 17.5% and the reduced price is £264.

Let the original price be '£x'.

So, (100 - 17.5)% = 82.5% of '£x' is  £264.

∴ (82.5/100)×x = 264.

0.825x = 264.

x = 264/0.825.

x =  £320.

So, The price reduced is (320 - 264) =  £56.

Answer:

1/7 ;

0.0034

Step-by-step explanation:

Given that:

X = 1/14, 1/7, 3/14

n = number of observations = 3

Since, probability of X is equally likely ;

P(X) = Σp(x) = 1 ; p(x) = 1/n = 1/3

The mean, m ;

Σx*p(x) = (1/3 * 1/14) + (1/3 * 1/7) + (1/3 * 3/14)

= 1/42 + 1/21 + 3/42

= (1 + 2 + 3) / 42

= 6 / 42

= 1/7

The variance :

Σx²*p(x) - m²

((1/3) * (1/14)^2) + ((1/3) * (1/7)^2) + ((1/3) * (3/14)^2) - (1/7)^2

= 0.0238095 - 0.0204081

= 0.0034014

Answer:

92

Step-by-step explanation:

The easiest way for me to find any percentage of a number is to find what 1% is and then multiply by the % amount. So to answer this question I would do 575/100 which is 5.75 and this is 1% then multiply 5.75 by 16 to get 92 so a 16% of 575 is 92. (Double check to make sure I'm correct)

Answer:

No solution

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

a) The value of x in equation (a) is x = 0.5.

b) The value of x in equation (b) is x = 0.02.

Let's solve the equations for the value of x:

a. X/5 + 20 = 20.1

Step 1: Subtract 20 from both sides to isolate the term with x:

X/5 = 20.1 - 20

Step 2: Simplify the right side:

X/5 = 0.1

Step 3: To solve for x, multiply both sides by 5:

X = 0.1 * 5

X = 0.5

So, the value of x in equation (a) is x = 0.5.

b. 5x + 20 = 20.1

Step 1: Subtract 20 from both sides to isolate the term with x:

5x = 20.1 - 20

Step 2: Simplify the right side:

5x = 0.1

Step 3: To solve for x, divide both sides by 5:

x = 0.1 / 5

x = 0.02

So, the value of x in equation (b) is x = 0.02.

a. mu_d = the true population mean difference in jump height

Step-by-step explanation:

In statistical parlance, observations used for a study could either be randomly chosen points or members of a large group or population, this small chosen observation obtained from a larger group is called the sample, the statistical measures or characteristic of such group is called statistic; while statistical characteristic, computations or measurement of the entire group of observations is called the parameter.

Mean of sample are usually represented with a bar sign on top such as (xbar) ; while mean of a population is represented as μ.

Answer:

0.0082 = 0.82% probability that the height of a randomly selected tree is as tall as mine or shorter.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Assume that X has a normal distribution with a mean of 191.8 ft and a standard deviation of 4 ft.

This means that [tex]\mu = 191.8, \sigma = 4[/tex]

A tree of this type grows in my backyard, and it stands 182.2 feet tall. Find the probability that the height of a randomly selected tree is as tall as mine or shorter.

This is the pvalue of Z when X = 182.2. So

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

[tex]Z = \frac{182.2 - 191.8}{4}[/tex]

[tex]Z = -2.4[/tex]

[tex]Z = -2.4[/tex] has a pvalue of 0.0082

0.0082 = 0.82% probability that the height of a randomly selected tree is as tall as mine or shorter.

Step-by-step explanation:

Number of insect on a randomly selected plant

The number of insect in such an experiment will be an integer value ;

Hence, sample space will be ;

{0, 1, 2, 3, 4, 5,....}

B.) Event of at most three insects:

Number of insects = 0 ;

Number of insect = 1 ;

Number of insect = 2 ;

Number of insect = 3 ;

n ≤ 3 {x : x ≤ 3}

{0, 1, 2, 3}

3.)

Each possible outcome in the sample space cannot be equally likely due to the fact that the number of insects on the selected plants will vary. With some plants having none to large number of insects while some have small amount of insects.
