please help asap! my geometry homework doesnt make sense
Answer:
50.4 in^2
66.4 in^2
Step-by-step explanation:
(L)= 6.3in
Area of base= (4)^2 =16 in^2
perimeter= 4×4 =16 in
L.A=1/2 ×p ×l
= 1/2×16×6.3=50.4 in^2
S.A=Base area + L.A
= 16+50.4=66.4 in^2

Answer:
LA = 20π square units
SA = 36π square units
V = 16π cubic units
Step-by-step explanation:
The value of the radius is needed before any area calculations can be done. It can be found from the Pythagorean theorem:
r² + 3² = 5²
r = √(25 -9) = 4
__
The lateral area is given by the formula ...
LA = πrs . . . . . where r is the radius and s is the slant height
LA = π(4)(5)
LA = 20π square units
__
The surface area is the sum of the lateral area and the base area. The latter is the area of a circle of radius 4.
SA = πr² + LA
SA = π(4²) +20π = 16π +20π
SA = 36π square units
__
The volume is given by the formula ...
V = 1/3πr²h
V = 1/3π(4²)(3) = 16π
The volume is 16π cubic units.
x=4 inches
y=10 inches
z=2 inches
Find the volume of the figure. Round to the hundredths place.
Answer:
i believe the answer is 142.42 in²
Step-by-step explanation:
what i did was 'separate' the cone and cylinder-
so the volume of cylinder formula is-
v=πr²h
and the volume for a cone is-
v=πr²h/3
now let us fill in the formulas with the information that we have-
v=π*2²*10=125.66
v=π*2²*4=16.76
now let us add the sums together-
125.66+16.76=142.42 in²
good luck :)

Answer:
Equation of a line at a distance of 2 units from xaxis is k = 2 So the locus is y = 2
what is the solution to the equation below 5+6•log2 x=14
The solutions to the equation 5 + 6 * log2(x) = 14 are x = 2√2 and x = -2√2.
To find the solution to the equation 5 + 6 * log2(x) = 14, we can solve it step by step:
Subtract 5 from both sides of the equation:
6 * log2(x) = 14 - 5
6 * log2(x) = 9
Divide both sides of the equation by 6:
log2(x) = 9/6
log2(x) = 3/2
Rewrite the equation in exponential form:
x = 2^(3/2)
Simplify the right side of the equation:
x = √(2^3)
x = √8
x = ±√(4 * 2)
x = ±2√2
Therefore, the solutions to the equation 5 + 6 * log2(x) = 14 are x = 2√2 and x = -2√2.

Problem 4: Price-fixing Litigation(5 points) Background: Multiple regression is sometimes used in litigation. In the case of Cargill,Inc. v. Hardin, the prosecution charged that the cash price of wheat was manipulated in violation of the Commodity Exchange Act. In a statistical study conducted for this case, a multiple regression model was developed to predict the price of wheat using three supply- and demand explanatory variables. Data for 14 years were used to construct the regression equation, and a prediction for the suspect period was computed from this equation. The value of R2 was 0.989. Problem: Cargill, Inc. had priced the wheat at $2.13. Their legal team needed to demonstrate that the price was not artificially depressed. For purposes of this project, suppose the sample size was 100. Requirements: 1.(2.5 points) For the relevant case, the fitted model gave the predicted value $2.136 with standard error $0.013. Based on this, determine the 95% prediction interval for the price of wheat. 2.(2.5 points)
Answer:
[tex]Critical\ value=1.66039[/tex]
Step-by-step explanation:
From the question we are told that:
Sample size [tex]n=100[/tex]
Mean price of wheat [tex]\=x=2.136[/tex]
Standard error [tex]S_e=$0.013[/tex]
95% prediction interval
Generally the equation for 95% confidence is mathematically given by
[tex]\alpha=1-95\%[/tex]
[tex]\alpha=1-0.95[/tex]
[tex]\alpha=0.05[/tex]
Generally the degree of freedom [tex]d_f[/tex] is mathematically given by
[tex]d_f=n-1[/tex]
[tex]d_f=100-1[/tex]
[tex]d_f=99[/tex]
Generally the critical [tex]t_{\alpha,df}[/tex] value is mathematically given by
[tex]t_{(0.05,99)}[/tex]
[tex]t_{(0.05,99)}=1.66039[/tex]
Therefore the critical associated with 95% predication interval is [tex]Critical\ value=1.66039[/tex]

Step-by-step explanation:
we are given a logarithmic equation
[tex] \displaystyle {5e}^{0.2x} = 6[/tex]
we want to figure out x
remember that,
[tex] \ln( {e}^{x} ) = x[/tex]
therefore to use the above formula with our given equation
divide both sides by 5:
[tex] \displaystyle \frac{{5e}^{0.2x} }{5}= \frac{6}{5} [/tex]
[tex] \displaystyle {e}^{0.2x} = \frac{6}{5} [/tex]
take In both sides:
[tex] \displaystyle \ln({e}^{0.2x} )= \ln \bigg(\frac{6}{5} \bigg)[/tex]
by using the formula we acquire
[tex] \displaystyle 0.2x= \ln \bigg(\frac{6}{5} \bigg)[/tex]
we can rewrite left hand side as fraction
[tex] \displaystyle \frac{1}{5} x= \ln \bigg(\frac{6}{5} \bigg)[/tex]
multiply both sides by 5
[tex] \displaystyle x=5 \ln \bigg(\frac{6}{5} \bigg)[/tex]

A Pew Research study finds that 23% of Americans use only a cell phone, and no land line, for making phone calls (The Wall Street Journal, October 14, 2010). A year later, a researcher samples 200 Americans and finds that 51 of them use only cell phones for making phone calls.Set up the hypotheses in order to determine whether the proportion of Americans who solely use cell phones to make phone calls differs from 23%.
Answer:
We accept H₀ sample does not give evidence to support that the proportion of Americans who solely use cell phone differs from 23 %
Step-by-step explanation:
A pew research finds that 23 % ( μ ) of Americans use only cell phone
Sample Information
sample size n = 200
x₁ = 51 then p₁ = 51/200 p₁ = 0,255
and q₁ = 1 - p ₁ q₁ = 1 - 0,255 q₁ = 0,745
Sample big enough for the approximation of the binomial distribution to the normal distribution
p₁*n = 0,255 * 200 = 51 > 5 and q₁*n = 0,745* 200 = 149 > 5
Test hypothesis
Null hypothesis H₀ p₁ = μ = 0,23
Alternative hypothesis Hₐ p₁ ≠ 0,23
Is a two tail test. We choose CI = 95 % then significance level is α = 0,05 %
α = 0,05 as is a two tail test α/2 = 0,025
from z-table z(c) = 1,96
To calculate z(s) = ( x - μ ) /√p₁*q₁/n
z(s) = ( 0,255 - 0,23 )/√0,255*0,745/200
z(s) = 0,025 / 0,0308
z(s) = 0,81
Comparing z(s) and z(c)
z(s) < z(c) 0,81 < 1,96
Then z(s) is in the acceptance region: we accept H₀
