Answer:
17.25
Step-by-step explanation:
A researcher uses an independent-measures t test to evaluate the mean difference between two treatments and obtains t(12) = 4.00. If the researcher had used an ANOVA to evaluate the data, what F-ratio would be obtained?
a. F(1, 11) = 2.00
b. F(1, 12) = 16.00
c. F(1, 12) = 2.00
d. F(1, 11) = 16.00
Answers
Answer:
B). F(1, 12) = 16.00
Step-by-step explanation:
'ANOVA' is a measure employed for 'analysis of a variance' in a given set of data of treatments or populations. While t-test helps in comparing their means.
As per the question, the F-ratio using ANOVA would be 'F(1, 12) = 16.00.' In order to calculate the variances, the distinction among the samples. The б^2 denotes the difference of representative means which is augmented by n(in case of samples being same). So, the ratio of F(1, 12) would be б^2 i.e. 4^2 = 16 since the sample sizes are distinct. Thus, option B is the correct answer.

find the volume of the following composite object. enter your answer as an integer in the box
Answers
Answer:
4082
Step-by-step explanation:
Given
The composite object
Required
The volume
The object is a mix of a cone and a hemisphere
Such that:
Cone
[tex]r = 10cm[/tex] ---- radius (r = 20/2)
[tex]h = 19cm[/tex]
Hemisphere
[tex]r=10cm[/tex]
The volume of the cone is:
[tex]V_1 = \frac{1}{3}\pi r^2h[/tex]
[tex]V_1 = \frac{1}{3}\pi * 10^2 * 19[/tex]
[tex]V_1 = \frac{1900}{3}\pi[/tex]
The volume of the hemisphere is:
[tex]V_2 = \frac{2}{3}\pi r^3[/tex]
[tex]V_2 = \frac{2}{3}\pi 10^3[/tex]
[tex]V_2 = \frac{2000}{3}\pi[/tex]
So, the volume of the object is:
[tex]V = V_1 + V_2[/tex]
[tex]V = \frac{1900}{3}\pi + \frac{2000}{3}\pi[/tex]
[tex]V = \frac{3900}{3}\pi[/tex]
[tex]V = 1300\pi[/tex]
[tex]V = 1300 * 3.14[/tex]
[tex]V = 4082[/tex]
The measure of _A is 18° greater than the measure of _B. The two angles are complementary. Find the
measure of each angle.
The m_A is
1° m
and m_B is
Answers
Answer:
angle A=54 degree
angle B =36 degree
Step-by-step explanation:
let angle B be x
angle A=x+18
since they are complementary angles sum of these two angles will be 90 degree
x+x+18=90
2x=90-18
2x=72
x=72/2
x=36 degree
substitute the value of x to find angle A and angle B
for angle A
x+18
36+18
54 degree
for angle B
angle B =x
=36 degree
1.Ramu deposited Rs. 10,000 in a bank where interest is compounded
half yearly. If the rate of interest is 10% annually. How much amount he
will get after a year?
3
Answers
Answer:
Future value, A = $10,500
Step-by-step explanation:
Given the following data;
Principal = Rs. 10,000
Interest rate compounded half yearly = 10% = 10/2 = 5%
Time = 1 year
To find the future value, we would use the compound interest formula;
[tex] A = P(1 + \frac{r}{100})^{t}[/tex]
Where;
A is the future value. P is the principal or starting amount. r is annual interest rate. n is the number of times the interest is compounded in a year. t is the number of years for the compound interest.Substituting into the equation, we have;
[tex] A = 10000(1 + \frac{5}{100})^{1}[/tex]
[tex] A = 10000(1 + 0.05)[/tex]
[tex] A = 10000(1.05)[/tex]
Future value, A = $10,500

The concentration of a pollutant in a lake is 85 parts per million (ppm) and is increasing at a rate of 4.6% each year. A possible formula for the concentration C as a function of year tis:

(c) C-85 +0.046t
(d) C-85 -0.046
(e) C = 85 (0.046)
(f) C-85 (0.954)
(g) C = 85 (1.046)
(h) C-85(1.46)
(i) C85(0.46)
(j) C-4.6 (0.85)
Answers
Answer:
[tex]C(t) = 85(1.046)^t[/tex], and the correct answer is given by option g.
Step-by-step explanation:
Equation for an concentration increasing exponentially:
The concentration after t years, considering that it increases exponentially, is given by the following equation:
[tex]C(t) = C(0)(1 + r)^t[/tex]
In which C(0) is the initial concentration and r is the growth rate, as a decimal.
The concentration of a pollutant in a lake is 85 parts per million (ppm) and is increasing at a rate of 4.6% each year.
This means that [tex]A(0) = 85, r = 0.046[/tex]. Thus
[tex]C(t) = C(0)(1 + r)^t[/tex]
[tex]C(t) = 85(1 + 0.046)^t[/tex]
[tex]C(t) = 85(1.046)^t[/tex], and the correct answer is given by option g.
