Answer: [tex]\$29.7[/tex]
Step-by-step explanation:
Given
The trophy has a side of [tex]a=9\ in.[/tex]
Slant height [tex]l=11\ in.[/tex]
Rate of painting [tex]r=\$\ 0.15/in.^2[/tex]
Lateral surface area of square pyramid is [tex]2al[/tex]
Insert the values
[tex]\Rightarrow 2\times 9\times 11\\\Rightarrow 198\ in.^2[/tex]
Cost of painting
[tex]\Rightarrow 198\times 0.15=\$29.7[/tex]
A farmer wants to know the effect of using various amounts of fertilizer in relation to the yield of his crops. He subdivided a portion of his land into 10 separate, but essentially equal, plots. He divided the land so that all of the plots had equal exposure to sun, rain, and other environmental conditions. He randomly selected 2 of the 10 plots and spread 2 pounds of fertilizer over each of them. Then he randomly selected 2 of the remaining plots and spread 3 pounds of fertilizer over each of them. He continued with the last sets of plots in the same manner, spreading 4, then 5, then 6 pounds of fertilizer over each of them. Below is a computer output for linear regression of amount of fertilizer versus yield for the 10 plots of land.
Predictor Coef SE Coef T P
Constant 10.100 0.7973 12.67 0.000
Fertizer 1.50 0.1879 6.12 0.000
S= 0.8404; R-Sq= 82.4% R-Sq(adj) = 80.28%

What is the equation of the least squares regression line from this sample?
Answer:
Y = 10.1 + 1.50x
Step-by-step explanation:
From the data contained in the computer output for linear regression
The coefficient of intercept = 10.1
coefficient of fertilizer = 1.50
Sample of an Equation of least squares regression line
y = a + bx
where : a = intercept , b = slope
hence the required equation will be
Y = 10.1 + 1.50x
y = yield , x = fertilizer

Statement first there was a ten-year age gap between the oldest and youngest students in 1990.and statement fourth are correct
What are population and sample?It is defined as the group of data having the same entity which is related to some problems. The sample is a subset of the population, it is a part of the population.
We have:
Survey data involving two random samples of students at law school are shown. The surveys were taken, comparing the age of students in 1900 to the age of students in 2014.
The statements that are true about the two samples of students:
In 1990, there was a 10-year age difference between the oldest and youngest students.In 2014, the median age of students was greater than the median age in 1990.Thus, statement first there was a ten-year age gap between the oldest and youngest students in 1990.and statement fourth are correct

solve the inequality 3/5x +30>150
Answer:
Step-by-step explanation:
3/5x+30=150
We move all terms to the left:
3/5x+30-(150)=0
Domain of the equation: 5x!=0
x!=0/5
x!=0
x∈R
We add all the numbers together, and all the variables
3/5x-120=0
We multiply all the terms by the denominator
-120*5x+3=0
Wy multiply elements
-600x+3=0
We move all terms containing x to the left, all other terms to the right
-600x=-3
x=-3/-600
x=1/200
What is the measure of arc BC?
9514 1404 393
Answer:
100°
Step-by-step explanation:
Arc BC is twice the measure of inscribed angle BEC, so is ...
arc BC = 2×50°
arc BC = 100°
Answer:
Step-by-step explanation:
The inscibed angle E is 1/2 the measure of the central angle P so P is 100 degrees, and arc BC is also 100 degrees.
What is the area of the figure composed of a parallelogram, a square, and a rectangle?
Answer:
Let's cut the figure into:
Parallelogram, square, and rectangle.
Let's find the area of the parallelogram first:
10 x 3.5 = 35
Let's find the area of the square:
4 x 4 = 16
When given one length of a square you already know are sides and lengths are equal so therefore 1 given length of a square is all the lengths.
Let's find the area of a rectangle:
6 x 12.5 = 75
Now let's add all the areas up:
35 + 16 + 75 = 126 square inches is your answer.

To build a computer, Tom needs to buy a motherboard for £ 120, and a CPU for
£ 100.Then find the total cost of building 10 computer ?
Answer:
£2200
Step-by-step explanation:
1 computer = £120 + £100
1 computer = £220
10 computers = £220 x 10
10 computers = £2200
A cone has a base radius of 3 cm and a slant height of 5 cm.
Find h, the perpendicular height of the cone.
Answer:
h=4
Step-by-step explanation:
5²-3²=h²
h²=16
h=4cm
Answer:
I=4 (Slant height)
R=3 (Radius)
H=5 (slant height)
Step-by-step explanation:
Imagine inclination, peprendicular height and radius as a triangle, so this will have a 90 degrees angle and Pythagor theorem will imply to the calculations, as :
[tex]a^{2}+b^{2}= c^{2}\\[/tex]
where Height is A , Radius is B, and Inclination is C we have:
[tex]3^{2} +I^{2} = 5^{2}[/tex]
from above we have:
[tex]I^{2} =25-9[/tex]
and
[tex]\sqrt{I}=\sqrt{16} =4[/tex]

Step-by-step explanation:
Given the following data;
A single fair die = 6
To find an outcome of A5;
Since the die was tossed just once, the outcome would be a fraction of the total number of outcomes.
P(A5) = number of times tossed/total number of outcomes
P(A5) = 1/6
make a flow chart showing that the two triangles are congruent. NO LINKS!
Answer:
Step-by-step explanation:
I take it the unmarked angle on the top triangle should be Q
The way the triangles are marked the following are the statements.
<Q = < X Given
RQ = XZ Given
XY = PQ Given
Is the angle included between the two given sides?
If yes then the Two Triangles are congruent by SAS
If no then the Two Triangles cannot be conclusively known to be congruent.
I have to leave you to figure out the flow chart symbols. I have no way of showing this as a flow chart if it is a computer program flow chart.

Answer:
Clearly, the probability of drawing a heart out of the deck is 13/52, or 1/4. The probability of drawing an even number as card #2 (∈{2,4,6,8,10}) for any suit is 20/51, except when the first card drawn is an even heart, then the probability of the second draw is 19/51.
With the spinner shown, the theoretical probability of landing on 2 is 0.25. Which number of spins would most likely result in a relative frequency that is closest to the theoretical probability?

find f(3) for the polynomial function F(x)=x^3-9x^2+5x-2
Answer:
f(3) = -41
Step-by-step explanation:
f(x) = x³-9x²+5x-2
now,
f(3) = 3³-9×(3)²+5×3-2
= 27-9×9+5×3-2
= 27-81+15-2
= -41
