A scientist is interested in the relationship between the number of eggs hatched per day for frogs (y) and temperature. Based on
the collected data, the least-squares regression line is ý = 15.66 +3.58x, where x is the number of degrees by which temperature
exceeds 60 degrees Fahrenheit. Which of the following statements best describes the meaning of the slope of the least-squares
regression line? (3 points)
For each increase of one degree Fahrenheit per day, there is an estimated increase of 15.66 hatched eggs.
O For each increase of one hatched egg, the estimated temperature per day increases by 15.66 degrees Fahrenheit.
O For each increase of one degree Fahrenheit per day, there is an estimated increase of 3.58 hatched eggs.
For each increase of one hatched egg, the estimated temperature per day increases by 3.58 degrees Fahrenheit.
The slope has no meaning because the units of measure for x and y are not the same.

Answers

Answer 1

There is an estimated rise of 3.58 hatched eggs for every one degree Fahrenheit increment every day. Then the correct option is B.

What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

In 2014 the population of Kenya was estimated to be 45,121,040 with a growth rate of 2.7%. Question 1 Use the exponential growth formula to write an equation that estimates the population y in terms of the time t. Enter your answer in the box. Then apply the exponential growth formula to estimate the population of Kenya in 2020. Round to the nearest whole number

Answers

Answer:

y = 45,121,040×1.027^t

Step-by-step explanation:

An exponential growth equation is generally of the form ...

 value at time t = (initial value)(growth factor)^t

where the growth factor is the multiplier for a period equal to one time unit.

Here, the initial value (in 2014) is 45,121,040. The growth factor is given as 1.027 (2.7% added per year), and we can define t as the number of years after 2014. Then our equation is ...

 y = 45,121,040×1.027^t . . . . where t = years after 2014

Choice C simplifies to 9n-8 for similar reasoning. The n+8n turns into 9n

This shows choices A and C are equivalent to choice D. Choice B isn't the same because 9(n-8) = 9n-9*8 = 9n-72. Use the distributive property.

- Five less a number is equal to two.

Answer:

Answer would be B

Step-by-step explanation:

First, A doesnt make sense, since it isn't a ineqality.

C doesnt make sense because if 5 is subtracted form a number n, it is -2, not 2.

D doesnt work because 5 less a number (-5) is not 2, it is -2.

Median: $2.06

Mode: $2.04

Variance: 0.0121

Standard Deviation: $0.1098

What is the range of the data for the 2018 data?

Range = maximum value - minimum value

Answers

The range is $0.39 which is the difference of the max value and min value.

What is the median?

A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.

We have data given:

Max: $2.42

Min: $2.03

Mean: $2.098

Median: $2.06

Mode: $2.04

Variance: 0.0121

As we know, the range = Max value—Min value

Here, Max = $2.42

Min = $2.03

Range = 2.42 - 2.03 = $0.39

Thus, the range is $0.39 which is the difference of the max value and min value.

Add both expressions

(-x²+2x+3) + (-x²-2x-1)

Expand

-x²+2x+3 -x²-2x-1

Find x and y.

Answers

4x = (130 - 2x) so x = 65/3

(3y + 40) + (130 -2x) = 180 because the angles are supplementary

plug in x

3y + 40 + 130 - 2(65/3) = 180

so 3y = 95/3

therefore y = 95/6
Answer:

x = -25
y = -13.33


Step-by-step explanation

To find x
(130 - 2x)° + 4x° = 180°
130 - 2x + 4x = 180
130 - 2x = 180
130 - 180 = 2x
x = -50 ÷ 2
x = -25 answer

To find y
(130 - 2x)° + (3y + 40)° = 180°
130 - 2x + 3y + 40 = 180
170 - 2x + 3y = 180
By putting the vaue of x in the equation
170 - 2(-25) + 3y = 180
170 + 50 + 3y = 180
3y = 180 - 170 - 50
y = -40 ÷ 3
y = -13.33 answer

What are Percentages?

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

The percentage of 4c that is equal to 0.04c can be found as,

x% of 4c = 0.04

(x/100) × 4c = 0.04
