The LA Dodgers hit the most home runs in 2014. The number of home runs accounted for 6% of the entire major league baseball home run count. If 583 total home runs were hit, then approximately how many did the LA Dodgers hit?
Answer: 39
Step-by-step explanation:
6% = .06 so .06 multiplied by 583 is 38.98 rounded is 39

The midline is y=
The amplitude is
The period is
Answer:
The midline is y=-1
Amplitude = 3
The period is 2 units
Step-by-step explanation:
Sinusoidal Function
It refers to a mathematical curve with a smooth and periodic oscillation. Its name comes from the sine function but it can be a cosine function too. They only differ by the phase angle of 90 degrees or π/2 radians.
The amplitude is half the distance from the maximum and the minimum points. The graph shows a sinusoid with a maximum value of y=2 and a minimum value of y=-4.
The amplitude is:
[tex]A=\frac{2+4}{2}=3[/tex]
Amplitude = 3
The midline is the distance from the center of the sinusoid to the x-axis. It's also called the vertical shift.
The midline can be found by subtracting the amplitude A=3 to the maximum value M=2:
ML = 2 - 3 = -1
It can also be found by adding the amplitude to the minimum value:
ML = -4 + 3 = -1
The midline is y=-1
The period is the time the wave takes to complete a full cycle. We only have to focus at any point on the wave (xo,yo) and find the next value of x where the sinusoid has the very same behavior (x1,y1). The period is then x1-x0.
We find at x=0, y=-1 and it's moving up. At x=1 it has the same value but it goes down, so the wave is at its half cycle. At x=2 it repeats the same behavior as for x=0. Thus:
The period is 2 units
A previous survey reported that 53% of respondents increased their portfolio value over the past 3 years. How large should a sample be if the margin of error is .03 for a 91% confidence interval
Answer:
A sample of 796 is needed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In this question, we have that:
[tex]\pi = 0.53[/tex]
91% confidence level
So [tex]\alpha = 0.09[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.09}{2} = 0.955[/tex], so [tex]Z = 1.695[/tex].
How large should a sample be if the margin of error is .03 for a 91% confidence interval
We need a sample of n, which is found when [tex]M = 0.03[/tex]. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.03 = 1.695\sqrt{\frac{0.53*0.47}{n}}[/tex]
[tex]0.03\sqrt{n} = 1.695\sqrt{0.53*0.47}[/tex]
[tex]\sqrt{n} = \frac{1.695\sqrt{0.53*0.47}}{0.03}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.695\sqrt{0.53*0.47}}{0.03})^{2}[/tex]
[tex]n = 795.2[/tex]
Rounding up
A sample of 796 is needed.

5y + 3 = 8y − 5 + 2y
Answer:
[tex] \fbox{y = 8/5 } [/tex]
Explanation:
[to solve for y, first use the properties of equality to simplify the equation]
5y + 3 = 8y − 5 + 2y
5y + 3 = (8y + 2y) – 5
[regroup the like terms of y together: commutative property of equality ; adding in a different order will still give you the same result]
5y + 3 = 10y – 5
[combine like terms]
5y + 3 = 10y – 5
[tex] \: \: \: \: \: \: -3 \: \: \: \: \: \: \: \: \: \: \: -3[/tex]
[subtract 3 from both sides in order to eliminate the constant term on the left side: subtraction property of equality]
5y = 10y – 8
–10y –10y
[subtract 10 from both sides in order to eliminate the variable term: subtraction property of equality]
-5y = -8
÷(-5) ÷(-5)
[divide both sides by -5 to cancel out the coefficient of y: division property of equality]
y = 8/5

On their vacation, Vanessa’s family drove 450 miles in 9 hours. Write and solve a proportion to show how long it would take them to drive 750 miles.
450/9 = 750/x
750 x 9 = 6,750
6,750/450 = 15
It would take them 15 hours to drive 750 miles.
Answer:
15
Step-by-step explanation:
Vanessa's family drove 450 in 9 hours
To find how many miles per hour
450/9 = 50
750/50 = 15
50 x 15 = 750

Which description best compares the graphs of the two functions below I ready
Answer:
Some of your pic is cut off so it's difficult to give the exact answer. But if you plot the points from the table you get that the equation for that set of data is linear and is y = 1/3x -2. This tells me that the y-intercepts are the same for both equations, so your answer is not the first or the third. Because the slope of the function A is 3 and for B is 1/3, the line for function A is steeper, the second of your choices above.

What is the equation of the line in slope-intercept form?
Answer:
The equation of the line in slope-intercept form is:
y = x + 4
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the points on the line graph
(0, 4)(1, 5)Determining the slope between (0, 4) and (1, 5)
(x₁, y₁) = (0, 4)
(x₂, y₂) = (1, 5)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [5 - 4] / [1 - 0]
= 1 / 1
= 1
Thus, the slope of the line = m = 1
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 4
Thus, the y-intercept b = 4
now substituting b = 4 and m = 1 in the slope-intercept form
y = mx + b
y = (1)x + 4
y = x + 4
Therefore, the the equation of the line in slope-intercept form is:
y = x + 4
Y=3x-1 is dilated by a scale factor of 4 and center at the origin what is the equation that represents the image of the line after the dilation
Answer: x=1/3y+1/3
Step-by-step explanation: Step 1: Flip the equation. 3x−1=y Step 2: Add 1 to both sides. 3x−1+1=y+1/3x=y+1 Step 3: Divide both sides by 3. 3x/3 = y+1/3 x= 1/3 y+ 1/3
You make six posters to hold up at a basketball game. Each poster has a letter of the word TIGERS You and five friends sit next to each other in a rowe
The posters are distributed at random. Find the probability that TIGERS is spelled correctly when you hold up the posters
Answer:
1/720
Step-by-step explanation:
there is only one way to spell tiger but there's 720 outcomes of the other words you can make
The probability that TIGERS is spelled correctly when you hold up the posters is 0.00139 approximately or 1/720 exactly.
How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]
where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.
For this case, the letters of TIGERS are given at random.
All the six letters are different and there exist 6! permutations for them. (as for n unique things, there exist n! possible arrangements of theirs).
So, the posters can be distributed in 6! = 6×5×4×3×2×1 = 720 ways.
Out of those 720 ways, there is only one correct way to spell TIGERS correctly.
Thus, we get:
P(event that correct order of posters is distributed) = [tex]\dfrac{1}{720} \approx 0.00139[/tex]
Thus, the probability that TIGERS is spelled correctly when you hold up the posters is 0.00139 approximately or 1/720 exactly.
