Answers
Answer:
A: 38º
Step-by-step explanation:
Triangle JKL is an isosceles triangle as JK=KL:
That means ∠J=∠L=71ºThe sum of a triangle's interior angles is 180º, so ∠K=180º-∠J-∠L. We know ∠J=∠L=71º, so ∠K=180º-71º-71º=38HELP WITH THIS QUESTIONS PLSSSSSS.

Step-by-step explanation:
-x³-3x²+6x+8=0
Multiply entire equation by -1:
x³+3x²-6x-8=0
Since x=2 is a solution, then x-2 must be a factor. Then:
x³+3x²-6x-8/x-2=x²+5x+4
x²+5x+4=0
Factor this:
x²+5x+4=(x+4)(x+1)=0
x=-4, -1

The mean weight of the domesticated house cat is 9.2 pounds with a standard deviation of 3.4 pounds. If a cat has a z-score of -1.3 for its weight, how much does it weigh? Write your answer as a complete sentence.
Answers
Answer:
4.78 pounds
Step-by-step explanation:
We solve the above question using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 9.2 pound
σ is the population standard deviation = 3.4 pounds
z = 1.3
We are to find x
Hence,
-1.3 = x - 9.2/3.4
Cross Multiply
-1.3 × 3.4 = x - 9.2
-4.42 = x - 9.2
x = -4.42 + 9.2
x = 4.78 pounds.
Therefore the weight of the cat is 4.78 pounds

Answers
Answer:
[tex]c = 2\sqrt{5[/tex]
Step-by-step explanation:
Given
[tex]a = 2[/tex]
[tex]b = 4[/tex]
c = hypotenuse
Required
Find c
Using Pythagoras theorem, we have:
[tex]c^2 = a^2 + b^2[/tex]
Substitute values for a and b
[tex]c^2 = 2^2 + 4^2[/tex]
[tex]c^2 = 4 + 16[/tex]
[tex]c^2 = 20[/tex]
Take square roots of both sides:
[tex]c = \sqrt{20[/tex]
Express 20 as 4 * 5
[tex]c = \sqrt{4 * 5[/tex]
Split surd
[tex]c = \sqrt{4} * \sqrt{5[/tex]
Take square root of 4
[tex]c = 2 * \sqrt{5[/tex]
[tex]c = 2\sqrt{5[/tex]
4. Which of the following formulas can be used to write 0.797979... as a fraction?
Answers
Answer:
The options are not shown, so i will answer this in a general way.
When we have a number like:
0.7979....
The steps to writing it as a fraction are the following ones:
1) First, you need to notice the repeating decimals.
In this case is easy to see that the repeating decimals are two, 7 - 9
2)we can multiply this number by 10^n, where n is the number of repeated decimals, in this case n = 2
10^2 = 100
then:
0.7979...*100 = 79.7979...
Now we can subtract the original number:
79.7979... - 0.7979 = 79
And this is equivalent to have:
0.7979..*100 - 0.7979... = 0.7979..*99 = 79
Then we know that if we multiply our number by 99, the outcome will be an integer.
Then we can multiply and divide by the same number (this is equivalent to multiply by one) as follows:
0.7979...*1 = 0.7979..*(99)/(99) = (0.7979..*99)/99 = 79/99
Then:
0.7979... = 79/99
Answer:
[tex]S_{inf.} - \frac{\frac{79}{100} }{1-\frac{1}{100} }[/tex]
Pretend "inf." is the infinity symbol, I couldn't put the actual symbol. It's option B.

In the past, the mean running time for a certain type of flashlight battery has been 9.7 hours. The manufacturer has introduced a change in the production method and wants to perform a hypothesis test to determine whether the mean running time has increased as a result. The hypotheses are: H 0: μ = 9.7 hours H a: μ > 9.7 hours where μ is the mean running time of the new batteries . Explain the meaning of a Type I error.

From the information given:

[tex]\mathbf{H_1: \mu > 9.7 \ hours}[/tex]
The type 1 error is rejecting [tex]\mathbf{H_o}[/tex] when
The meaning of Type 1 error is rejecting the claim that the mean running time is 9.7 hours when actually the mean running time is greater than 9. 7 hour.
