Find the probability of
1: choosing a yellow marble from a bag that contains 6 yellow marbles and 8 red marbles,
and
2: flipping a coin and it showing heads.

Answer: C. 11/102

Step-by-step explanation:

Given Data:

Red ball = 11

Blue ball = 7

Total no of balls = 18

What is the probability that choosing 4 balls all are red.

1. Probability of picking a red ball

  = 11/18

2. Probability of picking a blue ball

   = 7/18

3. Probability of picking 4 red balls in a roll.

  = 11/ 18 * 10/17 * 916  * 8/15

  = 11/102

  Or

10.8% chance of all 4 balls being red.

Answer:

a) Which number represents the rate at which the water level fell? -1.05mm/year

b) Which number should the rate be multiplied by to find the total variation in water level?

2.48 years

Step-by-step explanation:

Total variation in water level is calculated as the rate at which the water level fell multiplied by number of years are which the water level fell.

Mathematically = Rate at which the water level fell(mm/year) × number of years are which the water level fell (years).

Total variation in water levels can be caused by changes in climate conditions or by human activity.

Hence, for the question above,

rate at which the water level fell is

given as -1.05mm/year and the number that the rate be multiplied by to find the total variation in water level is 2.48 years.

Answer:

Which number represents the rate at which the water level fell?

✔ -1.05 mm/year

Which number should the rate be multiplied by to find the total variation in water level?

✔ 2.48 years

2820-28.2=2791.8

Answer:

1/2

Step-by-step explanation:

p(event) = (number of desired outcomes)/(total number of outcomes)

How many different outcomes are there? You can choose 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10, so the total number of possible outcomes is 10.

How many outcomes are desired. The desired outcomes are any outcomes with a number 6 or higher. Which numbers are 6 or higher? 6, 7, 8, 9, 10. There are 5 outcomes that are 6 or higher, so there are 5 desired outcomes.

p(event) = (number of desired outcomes)/(total number of outcomes)

p(event) = 5/10 = 1/2

Answer: 1/2

Answer:

The cost of a sheet metal per square foot is $30

Step-by-step explanation:

Given

Size of Sheet Metal = 8.2ft squared

Used Sheet Metal = 3.5ft squared

Worth of leftover sheet = $141

Equation: [tex]8.2x - 3.5x = 141[/tex]

Required

Find the cost per square foot of the sheet metal

Solving for x in the above equation will give the cost per square foot of the sheet metal.

[tex]8.2x - 3.5x = 141[/tex]

[tex]4.7x = 141[/tex]

Divide both sides by 4.7

[tex]\frac{4.7x}{4.7} = \frac{141}{4.7}[/tex]

[tex]x = \frac{141}{4.7}[/tex]

[tex]x = 30[/tex]

Hence, the cost of a sheet metal per square foot is $30

Answer:

1520.53

Step-by-step explanation:

V = pi * r^2 * h

Answer: 4.6

Step-by-step explanation:

GH is equal to 4.6 since it is congruent to JH. GJ is one line, which makes angles GKH and JKH supplementary angles. Since angle GKH = 90, angle JKH must also equal 90, making these triangles similar. However, if you wish to see it done out mathematically, the following explanation is there:

[tex]a^{2} + b^{2} = c^{2}[/tex]

3.6^2 + HK^2 = 4.6^2

HK^2 = 4.6^2 - 3.6^2

HK^2 = 8.2

HK = 2.86

HK^2 + GK^2 = GH^2

8.2 + 12.96 = GH^2

GH = 4.6

Answer:

R = 2.6 mm

Step-by-step explanation:

D = C ÷ π

D = 15.9 ÷ 3.14

D = 5.06

D = 5.1 mm

R = D ÷ 2

R = 5.1 ÷ 2

R = 2.55

R = 2.6 mm

Answer:

r = 2.5 mm

Step-by-step explanation:

The circumference of a circle has the following formula.

circumference = 2πr

where

r = radius

π = 3.14

circumference = 15.9 mm

circumference = 2πr

15.9 = 2 × 3.14 × r

15.9 = 6.28 r

divide both sides by 6.28

r = 15.9/6.28

r = 2.53184713376

Rounding to 1 decimal place

r = 2.5 mm

Answer:

100^2

Answer:

There is strong positive correlation between the size of a cell phone data plan and the number of text messages sent in the U.S.

Step-by-step explanation:

The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent). The correlation coefficient  value ranges from -1 to +1.

Positive correlation is an association amid two variables in which both variables change in the same direction.  

A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.

The closer the the correlation coefficient value gets to +1 or -1, the stronger relation becomes.

The correlation coefficient for the relationship  between the size of a cell phone data plan, x, and the number of text messages sent, y, is:

r = +0.97

The correlation coefficient is closer to +1.

Thus, there is strong positive correlation between the size of a cell phone data plan and the number of text messages sent in the U.S.
