Answer:

The circumference of the circle is about 166.42 cm.

The area of the circle is about 2205.07 cm².

Step-by-step explanation:

Diameter = 53 cm

Radius = r = 53cm/2 = 26.5 cm

π = 3.14

Circumference = C = 2 π r

C = 2(3.14)(26.5cm) = 166.42cm

The circumference of the circle is about 166.42cm.

Area = A = π r²

A = (3.14)(26.5cm)² = 2205.07 cm²

The area of the circle is about 2205.07 cm².

Answer:

a. 5 out of 21

b. (4.1811, 5.3589) 

Step-by-step explanation:

a. We can see from the stem plot that 5 out of the 21 tunas have dangerous levels of copper in their system because the copper level reached over 5.7, and the problem states "Dangerous levels of copper are classified when they reach beyond 5.7 parts per million" 

b. How to find it on calculator 

Step 1: [stat] 

Step 2: go to [tests] 

Step 3: go down to [7: zinterval] 

Step 4: make sure input is on [stats] 

Step 5: input the following 

: 1.16 

X (with the line above it): 4.77 

n: 21 

c-level: .98  

The solution is :

A.) The required proportion is 5/21=0.2381

B.) 98% confidence the true copper level (in parts per million) lies in the interval (4.13, 5.41).

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

here, we have,

A) From the stem-leaf plot, we see that out of 21 tunas, 5 have dangerous levels of copper since the levels go beyond 5.7 parts per million. The required proportion is 5/21=0.2381

B) Given the sample mean is {x}=4.77, sample standard deviation s=1.16 and the sample size is n=21.

Since the population standard deviation is not known, we use t-distribution.

So the 98% CI for mean is

4.77 ± t{1-0.02 /2,20} x 1.16/sqrt(21) = (4.13, 5.41)}

We are sure with 98% confidence the true copper level (in parts per million) lies in the interval (4.13, 5.41)

Step-by-step explanation:

Answer:

Z=34

Step-by-step explanation:

Answer:

z = 34

Step-by-step explanation:

Given

2 + 8 - z = -24

Combine Like Terms-

10 - z = -24

Rearrange Terms-

-z + 10 = -24

Subtract 10 from both sides

-z + 10 - 10 = -24 -10

Simplify

-z = -34

Divide -1 from both sides

-z/-1 = -34/-1

Answer-

z = 34

Answer:

The probability is 1/18.

Step-by-step explanation:

There are 10 balls in total. Let's start with the probability of just the green. There is 1 green ball.out of 10 balls total, so the probability of pickin just the green one would be 1/10. Since we aren't replacing the balls after we choose them, the total number of balls is now 9. now the probability of picking one yellow ball out of the nine balls left is 5/9 because there are 5 yellow balls. To get the probability of the green and yellow balls picked, we multiply the individual probabilities to get the actual probability of choosinf one green and one yellow ball without replacement. So multiply 1/10×5/9= 5/90, simplified to 1/18.

Two balls are selected at random, the probability of choosing two balls 1 green and 1 yellow without replacement is 1 / 20

What information do we have?

Number of green balls = 1

Number of red balls = 4

Number of yellow balls = 5

Total number of balls = 1 + 4 + 5 = 10

Probability of green ball = 1 / 10

Probability of yellow ball = 5 / 10

Probability if there is no replacement of P(1 green and 1 yellow) = (1/10)(5/10)

Probability if there is no replacement of P(1 green and 1 yellow) = 1 / 20

Step-by-step explanation:

1st year-> 30000

2nd year-> 31800

3rd year ->33708

4th year->35730.48

5th year -> 37874.3088

37874.3088+35730.48+33708+31800+30000= 169112.7888

                                                                             ≈ 169113

The solution is Option C.

The total amount of earnings of Sondra after 5 years is $ 169,113

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the annual salary of Sandra be A = $ 30,000

Now , the percentage increase in salary = 6 %

So , the equation will be

First year :

The increase in first year =  annual salary of Sandra + percentage increase in salary x annual salary of Sandra

The increase in first year = 30000 + ( 6/100 ) x 30000

                                         = 30000 + 1800

                                         = $ 31,800

Second year :

The increase in second year =  increase in first year + percentage increase in salary x increase in first year

The increase in second year = 31800 + ( 6/100 ) x 31800

                                         = 31800 + 1908

                                         = $ 33,708

Third year :

The increase in third year =  increase in second year + percentage increase in salary x increase in second year

The increase in third year = 33708 + ( 6/100 ) x 33708

                                         = 33708 + 2022.48

                                         = $ 35,730.48

Fourth year :

The increase in fourth year =  increase in third year + percentage increase in salary x increase in third year

The increase in fourth year = 35730.48 + ( 6/100 ) x 35730.48

                                         = 35730.48 + 2143.8288

                                         = $ 37,874.3088

Now , the equation is

The total earnings of Sondra is = First year salary + second year salary + third year salary + fourth year salary

The total earnings of Sondra is = 30000 + 31,800 + 33,708 + 35,730.48 + 37,874.3088

The total amount earnings of Sondra is = $ 169,112.7888

Therefore , the total amount earnings = $ 169,113

Hence , The total amount of earnings of Sondra after 5 years is $ 169,113

D) x=6√3, y=3√3

Step-by-step explanation:

Given both triangles are 30-60-90 triangles, this means that the length of y will be 9/√3=√81/√3=√(81/3)=√27=3√3

This also means that x will be twice the length of y which means x=2y=2(3√3)=6√3

This means that the correct answer is D) x=6√3, y=3√3
