Answer:
The values that are solutions to K-3 >-2 are -7 and -5. To solve this inequality, we need to isolate the K term on one side of the inequality. We can do this by subtracting 3 from both sides of the inequality, like this:
K - 3 > -2
K - 3 - 3 > -2 - 3
K > -5
Therefore, the solutions to the inequality K-3 >-2 are all values of K that are greater than -5. This means that the values -7 and -5 are solutions to the inequality, but the other values listed are not.

suppose a 90% confidence interval for the population mean resulted in an upper limit of $658 and a lower limit of $273. what is the correct interpretation of this confidence interval? question 5 options: 1) we are 90% confident the population mean is in this interval. 2) there is a .90 probability the population mean is in this interval. 3) we are 90% confident the population proportion is in this interval. 4) there is a .90 probability the sample mean is in this interval.
The correct interpretation of this confidence interval is that "we are 90% confident the population mean is in this interval." This means that if we were to repeat the sampling process many times, we would expect that 90% of the resulting confidence intervals would contain the true population mean.
What does 1.022 represent in the expression?
Because b > 1, the correct response in this situation would be: "1.022 is the growth factor for the GDP since 1950, and the GDP increases by a factor of 1.022 every year."
In this instance, we're assuming that we can use the following function to simulate the US GDP, or gross domestic product, in dollars:
[tex]GDP = 11(1.0220)^{t}[/tex]
We can also see that the exponential model formula given by: governs this formula.
[tex]GDP = 11(1.0220)^{t[/tex]
Where a denotes the starting sum, b the model's growth/decay rate, and t is the number of years since 1950.
The value of b in this instance is provided by:
b = 1.022
And when we calculated r as the growth rate, we obtained:
1.022 = 1 + r
r = 1.022 - 1
r = 0.022

It rained 1.5 inches in Drake City yesterday. The meteorologist's rainfall prediction was 20% less than that. How much rainfall did the meteorologist predict?
Answer:
Step-by-step explanation
To find the amount of rain the meteorologist predicted, start by listing the key information from the problem.
The actual amount of rain was 1.5 inches.
The meteorologist's prediction was 20% less than that. This is the percent error.
First, find the amount of error. It is 20% of the actual amount of rain.
0.21.5=0.3
So, the amount of error in the meteorologist's prediction is 0.3 inches. Since the predicted amount was less than the actual amount, subtract 0.3 from the actual amount of rain.
1.5–0.3=1.2
The meteorologist predicted 1.2 inches of rainfall.
You could also find the meteorologist's rainfall prediction by finding 80% of the actual amount of rain.
0.81.5=1.2
The amount of rainfall the meteorologist predict is 1.2 inches
How to determine how much rainfall the meteorologist predict?From the question, we have the following parameters that can be used in our computation:
Amount of rainfall = 1.5 inches
Prediction = 20% less than the amount of rainfall
These parameters imply that:
Prediction = Amount of rainfall * (1 - Percentage less)
Substitute the known values in the above equation, so, we have the following representation
Prediction = 1.5 * (1 - 20%)
Evaluate
Prediction = 1.2
Hence, the prediction is 1.2 inches

If you start with 1 and repeatedly multiply by 1/2, will you reach 0? Explain why or why not.
Answer:
nope
Step-by-step explanation:
1 multiplied by 1/2 just equals 1/2 since it's being multiplied by one, it wouldn't matter if you kept multiplying 1/2 either because the numerator will stay the same regardless, and the denominator just gets bigger and bigger since you're multiplying by two. if the numerator wasn't 1 then I'm sure there's a possibility, but in this scenario, it's not.
Answer: You will reach 0
Step-by-step explanation:
Yes, if you start with 1 and repeatedly multiply by 1/2, you will reach 0.
To see why this is the case, let's consider the following sequence of numbers:
1 * (1/2) = 0.5
0.5 * (1/2) = 0.25
0.25 * (1/2) = 0.125
0.125 * (1/2) = 0.0625
0.0625 * (1/2) = 0.03125
As you can see, each time we multiply by 1/2, the result is half of the previous number. Because any number multiplied by 0 is 0, we will eventually reach 0 if we keep multiplying by 1/2.
Therefore, if you start with 1 and repeatedly multiply by 1/2, you will reach 0.

Answer: 63
Step-by-step explanation:
Let's start with what we know. A straight line measures an angle of 180. So, at point m, we have one degree measuring 118. We do:
180 - 118 = 62
So, 62, is the angle in the corner.
We also know that the sum of the angles in a triangle = 180 so:
10x - 2 + 62 = 180
10x + 60 = 180
10x = 120
x = 12
So angle K is 63.

What is the slope of a line perpendicular to the line whose equation is 3x+3y=18. Fully simplify your answer.
The slope of a line is -1
What is a line ?
A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Since lines can exist in two, three, or higher dimensional environments, they are one-dimensional things. The term "line" can also be used to describe a line segment in daily life that contains two locations that serve as its ends.
A line is a perfectly straight, one-dimensional shape that extends infinitely in both directions and has no thickness. In order to stress that a line has no "wiggles" anywhere along its length, it is occasionally referred to as a straight line or, more formally, a right line (Casey 1893).
y = mx + c
Subtract 3x from both sides of the equation
