Answer:

3/1

Step-by-step explanation:

You would count how far up it goes, with out it passing the dot (also know as the rise) which in this case is 3. Then you would count the number of space to go to the side (the run) so in this case it would be 1. Finally you would put rise over run and get 3/1.

Answer:

Slope = \frac{3}{1}

Step-by-step explanation:

Slope Formula= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

We take two point from the line that is (1,1) & (2,4)

Putting the points in the formula we get,

Slope Formula= \frac{4-1}{2-1} = 3

Find the perimeter of a circle whose radius is 3.5cm. (Take pi = 22/7)
mrs_skeptik [129]

Answer:

P = 44

The formula for the perimeter (circumference) of a circle is;

C = πd

C = 2πr

C = 2π (3.5)2

C = 2π7

C = 2 * 22/7 * 7

C = 2 * 22

C = 44

A survey of several 9 to 11 year olds recorded the following amounts spent on a trip to the mall: $10.31,$17.22,$26.62,$22.84 Co
dimaraw [331]

Answer:

Step-by-step explanation:

From the information given,

Mean, μ = (10.31 + 17.22 + 26.62 + 22.84)/4 = 19.2475

Standard deviation, σ = √summation(x - mean)/n

Summation(x - mean) = (10.31 - 19.2475)^2+ (17.22 - 19.2475)^2 + (26.62 - 19.2475)^2 + (22.84 - 19.2475)^2 = 151.249475

σ = √(151.249475/4)

σ = 6.15

number of sample, n = 4

The z score for 98% confidence interval is 2.33

We will apply the formula

Confidence interval

= mean ± z ×standard deviation/√n

It becomes

19.2475 ± 2.33 × 6.15/√4

= 19.2475 ± 2.33 × 3.075

= 19.2475 ± 7.16

The lower end of the confidence interval is 19.2475 - 7.16 = 12.09

The upper end of the confidence interval is 19.2475 + 7.16 = 26.41
