in your sock drawer, you have 12 blue socks and 12 yellow socks. It is dark in the morning when you were getting dressed, and you can’t see the color of the socks. What is the probability of randomly picking a yellow sock?

A.) 1/23
B.) 1/2
C.) 1/12
D.) 1/11
E.) 1/24

Answers

Answer 1

Answer:

1/2

Step-by-step explanation:

There are 12+12 = 24 socks in the drawer

P(yellow) = number of yellow socks/ total socks

                = 12/24

                =1/2

4. In the U.S., from 2004 - 2015, 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. Describe the relationship between the data


plan size and the number of text messages sent in the U.S.

Answers

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.

A contractor bought 8.2 ftsquared of sheet metal. She has used 3.5 ftsquared so far and has ​$141 worth of sheet metal remaining. The equation 8.2xminus3.5xequals141 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square​ foot?

Answers

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

Mr. Whittaker’s science class uses tide gauges to measure annual variations in water levels at different parts of a river, and then compares those variations to the average annual trend.

Matea recorded that the water level in one part of the river fell 1.05 millimeters per year for 2.48 years.

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


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

2.48 years


that's the correct answer ^
This data will be compared to the average annual trend, which shows the water level rising 1.8 mm/year.

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

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

Answers

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

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

i will give you brainiest if you can can answer in 3 minutes

Answers

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

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]

HK^2 = 4.6^2 - 3.6^2

HK^2 + GK^2 = GH^2

8.2 + 12.96 = GH^2

A number is chosen at random from 1 to 10. Find the probability of selecting a 6 or greater.

Answers

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)
