Answer 1

The table that shows the relationship between the weights of pints of blueberries is a linear regression function

The equation of the line is y = 0.75xTen pints of blueberries weigh about 7.5 pounds.Ten pints of blueberries will cost about $16.875

The graph

The table entry is given as:

x 0 1 2 3 4 5

y 0 0.8 1.50 2.20 3.0 3.80

See attachment for the graph

The points on the line

A line that could best approximate the points could go through the origin (0,0) and (5,3.75)

The line equation

We have the points to be (0,0) and (5,3.75)

Since the line passes through the origin, the equation of the line would be:

[tex]y = \frac{y_2}{x_2}x[/tex]

So, we have:

[tex]y = \frac{3.75}{5}x[/tex]

[tex]y = 0.75x[/tex]

Hence, the equation of the line is y = 0.75x

The weight of 10 pints of blueberries

This means that x = 10.

So, we have:

y = 0.75 * 10

y = 7.5

Hence, ten pints of blueberries weigh about 7.5 pounds.

The cost of 10 pints of blueberries

The unit rate is $2.25 per pound

Ten pints of blueberries weigh about 7.5 pounds.

So, the cost of 10 pints is:

Cost = 7.5 * 2.25

Cost = 16.875

Ten pints of blueberries will cost about $16.875

which numbers for b would make √b irrational

mark as brilliant!

Answers

Answer:

All of the options when substituted for b will make the root of b irrational

Step-by-step explanation:

Mathematically, surds are roots of non-perfect squares and they are tagged as irrational numbers

For b to be irrational, all of the numbers given would fit. This is because all of these numbers are non-perfect squares meaning they do not have square root.

So what this mean is that these numbers when put under the root umbrella are irrational numbers as they are not perfect squares

What is ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given measurements,

2 feet and 40 inches

1 feet = 12 inches

2 feet = 24 inches

Ratio of 2 feet to 40 inches = 24/40

= 3/5

Suppose you anticipate needing to call the UK for a total of 250 minutes and France for 100 minutes. Will a $75 card cover the cost of this much calling? Explain your answer.

Answers

Complete question :

You have relatives living in the United Kingdom and in France. Suppose that you have purchased a prepaid phone card with a value of $75. Calls to the United Kingdom cost 23¢ per minute, while calls to France cost 21¢ per minute."Suppose you anticipate needing to call the UK for a total of 250 minutes and France for 100 minutes. Will a $75 card cover the cost of this much calling?

Answer:

cell phone card won't be enough.

Step-by-step explanation:

Cell phone card value = $75

United kingdom = 23cent per minute

France = 21 cent per minute

United Kingdom minutes = 250

France minutes = 100

Total cost :

23 cent = $0.23

21 cent = $0.21

Total :

United Kingdom = 0.23 * 250 = $57.5

France = 0.21 * 100 = $21

$21 + $57.5 = $78.5

$78.5 > $75

Then, it can be concluded that the cell phone card won't be enough.

An information technology company produces 45% of its computer chips at a plant in St. Louis and the remainder of its chips at a plant in Chicago. It is known that 0.85% of the chips produced in St. Louis are defective, while 1.05% of the chips produced at the plan in Chicago are defective. What is the probability that a randomly chosen computer chip produced by this company is defective and was produced in St. Louis?

Answers

Answer:

the probability of the computer chip produced and defective is 0.003825

Step-by-step explanation:

The computation of the probability of the computer chip produced and defective is shown below

= Produced percentage × defective percentage

= 45% × 0.85%

= 0.003825

Step-by-step explanation:

Whole numbers are all positive numbers including 0. However, these numbers cannot have fractions or decimals. Integers include numbers that are negative and positive, however they cannot have fractions or decimals either. 0 counts as an integer, too. Rational numbers are numbers that can be written as a fraction. Decimals can be rational, too - they just have to either terminate (end at some point) or repeat. Knowing these rules...

-98 would qualify as an integer and a rational number - but not a whole number because it's negative. Row I is correct. 0 would qualify as an integer, whole number, and rational number. Row I is correct. -0.7878... would not qualify as an integer or whole number - it is a decimal - but it would qualify as a rational number since it repeats. Therefore, Row III is wrong. [tex]2\frac{15}{17}[/tex] would not qualify as an integer or whole number - it is a fraction - but it would qualify as a rational number. It can be written as a fraction. Row IV is correct. 10.5 would not qualify as an integer or whole number - it is a decimal number - but it could be rational since it can be written as [tex]10 \frac{1}{2}[/tex]. Row V is wrong.

Hey there!

The answer to your question is 5/38

We can find this answer by taking the total group and subtracting all the data to see how many are left who don't play either:

38 - 14 - 8 - 11

This means that 5 out of every 38 pupils do not play either instrument, so the probability would be 5/38.

Step-by-step explanation:

The above question is in the form of an exponential decay. The equation for an exponential decay is given by:

[tex]y=ab^x[/tex]

where y and x are variables, b < 1, a is the initial value of y (that is the value of y when x = 0).

Let y represent the number of trees left and x represent the number of months. Given that there is currently 2.5 billion trees, therefore a = 2.5 * 10⁹, b = 0.5% = 0.005. The equations becomes:
