Answer:
A. y = 91.1765x - 346.5708B. 64 lbsStep-by-step explanation:
Part AUse the data in the table to get the best fit line, with equation:
y = mx + bTo do so follow the steps:
1. Let the Height be x and the Weight be y
Sum x and y
∑x = 5.3 + 5.4 + 5.3 + 6 = 22∑y = 140 + 150 + 130 + 200 = 6202. Sum x² and xy
∑x² = 5.3² + 5.4² + 5.3² + 6² = 121.34∑xy = 5.3*140 + 5.4*150 + 5.3*130 + 6*200 = 34413. Calculate m, considering n = 4 (number of data values)
m = (n∑xy -∑x∑y)/(n∑x² - (∑x)²) = (4*3441 - 22*620)/(4*121.34 - 22²) = 124/1.36 = 91.17654. Calculate b:
b = (∑y - m∑x)/n =(620 - 91.1765*22)/4 = -1385.883 /4 =-346.4708We got the best line fit formula:
y = 91.1765x - 346.5708Part BFinding y for x = 4.5:
y = 91.1765*4.5 - 346.5708 = 63.72345 ≈ 64 lbsEvaluate b*2−16a+5 when a=1/2 and b=7.

Express in simplest radical form.
V63
Answer:
Step-by-step explanation:
If you mean √63, you are better off not using a random symbol to represent √.
"Square root of 63" is much clearer.
Factor the radicand, then take the square root of the factors.
√63 = √(3²·7) = √3²· √7 = 3√7

Solve the equations in Parts A and B using inverse operations. Check your solutions. In your final answer, include all of your work.
Part A:
[tex]2x^2+5=13[/tex]
Part B:
[tex]2x^{3} - 13 = 5[/tex]
Answer:
A) ±2
B) 2.08
Step-by-step explanation:
A) Given the equation
2x² + 5 = 13
Add the additive inverse of 5 to both sides
2x² + 5 + (-5) = 13 + (-5)
2x² + 5 - 5 = 13 - 5
2x² = 8
x² = 4
x= ±√4
x = ±2
Hence the value of x is ±2
b) 2x³-13 = 5
Add the additive inverse of -13 to both sides
2x³-13 + 13 = 5 +13
2x³ = 18
x³ = 18/2
x³ = 9
x = ∛9
x= 2.08
Hence the value of x is 2.08

A bar of platinum has a length of 49.7 millimeters, a width of 28.5 millimeters, and a height of 3.4 millimeters. Describe how
doubling the length and width affects the volume.
Answer: the volume is 2 times bigger
Step-by-step explanation:
9631.86/4815.93
Volume of new bar will be increase 4 times
Give information:
Length of bar = 49.7 mm
Width of bar = 28.5 mm
Height of bar = 3.4 mm
New Length of bar = 2 × 49.7 = 99.4 mm
New Width of bar = 2 × 28.5 = 57 mm
Find:
Effect on the volume
Computation:
Volume of cuboid = l × b × h
So,
Volume of bar = 49.7 × 28.5 × 3.4
Volume of bar = 4,815.93 mm³
Volume of new bar = 99.4 × 57 × 3.4
Volume of new bar = 19,263.72 mm³
Effect on the volume = Volume of new bar / Volume of bar
Effect on the volume = 19,263.72 / 4815.93
Effect on the volume = 4 times
So,
Volume will be increase 4 times

The random variable X is exponentially distributed, where X represents the waiting time to see a shooting star during a meteor shower. If X has an average value of 85 seconds, what are the parameters of the exponential distribution
Answer:
the parameters are [tex]\lambda = \frac{1}{85} , \mu = 85, \sigma = 85[/tex]
Step-by-step explanation:
The computation of the parameters of the exponential distribution is as follows:
Given that
X has an average value of 85 seconds
So, [tex]\mu[/tex] = mean = 85
[tex]\lambda = \frac{1}{\mu}\\\\= \frac{1}{85}[/tex]
[tex]\sigma = \mu = 85[/tex]
In the case of the exponential distribution, the mean would be equivalent to the standard deviation
So, the parameters are [tex]\lambda = \frac{1}{85} , \mu = 85, \sigma = 85[/tex]

The volume of this cylinder is 2700π(cubed)
Find the length of the radius, r.
Give your answer as a surd in its simplest form.
r ?
150cm is the height
Given that,
The volume of the cylinder, [tex]V=2700\pi\ cm^3[/tex]
The height of the cylinder, h = 150 cm
To find,
The radius of the cylinder.
Solution,
The formula for the volume of the cylinder is given by :
[tex]V=\pi r^2 h\\\\r=\sqrt{\dfrac{V}{\pi h}}\\\\r=\sqrt{\dfrac{2700\pi }{\pi \times 150}}\\\\r=4.24\ cm[/tex]
So, the radius of the cylinder is 4.24 cm.
A cognitive psychologist studying reading comprehension wanted to know what would happen if all college students were taught better reading strategies. She obtained a sample of 40 college students from the introductory psychology class and taught 20 of them effective reading strategies. The other 20 students were given a placebo treatment. She then gave all 40 students a standardized reading comprehension test. The mean score on the reading test for those taught the reading strategies was 49, with a standard deviation of 4 The mean score for those receiving the placebo treatment was 44, with a standard deviation of 3.8. Identi the independent variable in this study.
A) scores on the reading comprchension test
B) the sample of 40 college students
C) the reading strategies class
D) the treatment group (placebo or reading strategies)
Answer:
D.the treatment group (placebo or reading strategies)
Step-by-step explanation:
This cognitive psychologists wants to find out if better reading strategies when taught to students would have any effect on their test scores.
So the dependent variable in this experiment would be the test scores that she wants to find from the test.
While the independent variable would be the treatment group which is the placebo or treatment. The psychologist wants to measure outcomes in this dependent variable using changes in the independent variable (placebo/treatment).
