Answer: Katherine should reject the null hypothesis.
Step-by-step explanation:
We reject the null hypothesis when p-value is less than the significance level.
here, H0:μ=329 versus Ha:μ<329
α=0.05 (significance level)
p-value<0.005
so , we should reject the null hypothesis as p-value is less than the significance level.
Hence, Katherine should reject the null hypothesis.
Dan loves to compete in triathlons. At a race a few months ago, he finished in 300 minutes. Yesterday, he completed another triathlon and finished in 306 minutes. What was the percent of increase in Dan's finishing time?
Answer:
2%
Step-by-step explanation:
If 300 minutes is 100%, how much percent is 306 minutes?
we need to use the rule of three
306 minutes x 100% / 300 minutes = 102%
Therefore the percent of the increase is 102%-100%= 2%
What is the equation of the line that passes through the point (-6,-5) and has a slope of 3/2
Answer: actual answer is y=3/2x+4
Step-by-step explanation: plug b in the original formula
The equation of the line as of the condition given is y = 3x/2 + 3/2.
Given that,
The equation of the line that passes through the point (-6,-5) and has a slope of 3/2 is to be determined.
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The point-slope form of the line is given as,
y - y₁ = m (x - x₁)
From the given substitute the point and slope in the above equation,
y + 6 = 3/2 [x + 5]
y = 3x/2 + 15/2 - 6
y = 3x/2 + 3/2
Thus, the equation of the line as of the condition given is y = 3x/2 + 3/2.

Lines e and f are intersected by lines a and b. At the intersection of lines a and e, the uppercase right angle is 110 degrees. At the intersection of lines b and e, the uppercase right angle is 110 degrees. At the intersection of lines b and f, the bottom right angle is 80 degrees.
Which lines are parallel? Justify your answer.
Lines a and b are parallel because their corresponding angles are congruent.
Lines a and b are parallel because their same side exterior angles are congruent.
Lines e and f are parallel because their corresponding angles are congruent.
Lines e and f are parallel because their same side exterior angles are supplementary.
Answer:
D. Lines e and f are parallel because their same side exterior angles are supplementary.
Step-by-step explanation:
I know for a fact that it is not C or A even though those ones would make the most sense. This leaves B and D; It's not B because is said that angles A and B are both exterior which is incorrect, A in interior and B is Exterior. This leaves us with D as our final answer.
Hope this helps, may I get brainliest please? :)
The parallel lines are; Lines e and f are parallel because their same side exterior angles are supplementary.
How are parallel straight lines related?Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.
Since the given parallel line has equation y = 4x + 2, thus its slope is 4 and thus, the slope of the needed line is 4.
We have given that Lines e and f are intersected by lines a and b.
At the intersection of lines a and e, the uppercase right angle is 110 degrees. The lines b and e, the uppercase right angle is 110 degrees. The lines b and f, the bottom right angle is 80 degrees.
Therefore, The parallel lines is; Lines e and f are parallel because their same side exterior angles are supplementary.

(-8+4i)(1 - i)
Which of the following is equivalent to the complex number shown above?
Note: i = -1
Answer:
-4 + 12i
Step-by-step explanation:
(-8 + 4i) (1 − i)
Distribute using FOIL.
(-8)(1) + (-8)(-i) + (4i)(1) + (4i)(-i)
-8 + 8i + 4i − 4i²
-8 + 12i + 4
-4 + 12i
The product of two complex numbers (-8+4i) and (1 - i) is - 4(1 + i).
What is a complex number?"A complex number is a number of the form a + bi, where 'a' and 'b' are real numbers. Here, i = √(- 1)."
Given, (- 8 + 4i)(1 - i)
= (- 8 + 4i - 8i - 4i²)
= [- 8 - 4i - 4(- 1)]
= (- 8 - 4i + 4)

Intelligence Quotient (IQ) scores are often reported to be normally distributed with μ=100.0 and σ=15.0. A random sample of 59 people is taken. Step 1 of 2 : What is the probability of a random person on the street having an IQ score of less than 98 ? Round your answer to 4 decimal places, if necessary.
Using the normal distribution, it is found that there is a 0.4483 = 44.83% probability of a random person on the street having an IQ score of less than 98.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, the mean and the standard deviation are, respectively, given by [tex]\mu = 100[/tex] and [tex]\sigma = 15[/tex].
The probability of a random person on the street having an IQ score of less than 98 is the p-value of Z when X = 98, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{98 - 100}{15}[/tex]
[tex]Z = -0.13[/tex]
[tex]Z = -0.13[/tex] has a p-value of 0.4483.
0.4483 = 44.83% probability of a random person on the street having an IQ score of less than 98.

4 A game is being watched by 60 adults and some
children. If there are 20 more adults than children,
how many children are watching the game?
Lo Children
Answer:
20 children.
Step-by-step explanation:
We can solve this using an equation or simple mental math:
The equation: x=children x+20=adults
x + (x+20) = 60
2x + 20 = 60
2x = 40
x = 20
Mental Math: 40 plus 20 is 60 and 40 is 20 more than 20 so there are 40 adults and 20 children.

Well basically I did 70 - inequality and got 2 and when I subtracted those numbers it gave me 3 and then I added 3 + 2 and got 5 and then when I did 5 + 3 + 2 I got 80 and then I said thats to much so I divided 80 by 5 and got 33. and I thought 33 was to little so I added an extra 20 and got 60
