Answer:
D. A two-sample t-test for a difference between population means
Step-by-step explanation:
Since in the question it is mentioned that there would be the random samples taken from each population of raccons and the weight of the mean sample would be determined for each kind of sample
So here the test for the study that should be considered is two sample t-test so that it would create a difference between the population means
Hence, the option d is correct
Which of the following is the function representing the graph below?
a. f(x) = 4x
b. f(x) = 4x − 3
c. f(x) = 4x + 3
d. f(x) = 4(x + 3)
Answer:
d. f(x) = 4(x + 3)
pleaseeeeee help me out quickkk solve for x
Answer:
x = 27.2
Step-by-step explanation:
Apply trigonometric function to solve for x.
Reference angle = 54°
Side length opposite to reference angle = 22
Hypotenuse = x
We would apply SOH:
Sin 54 = Opp/Hyp
Sin 54 = 22/x
x*sin 54 = 22
x = 22/sin 54
x = 27.1934955 ≈ 27.2 (nearest tenth)
What are the zeros of x^3 + 16x^2 + 60x? What are their multiplicities?

I NEED HELP FAST THANK YOU
Answer:
D
Step-by-step explanation:
round 36 to the nearest hundredth. for the brainiest
36 to the nearest hundredth is just 36
To round 36 to the nearest hundredth consider the thousandths' value of 36, which is 0 and less than 5. Therefore, the hundredths' value of 36 remains 36
Answer:
Round 36 to the nearest tenth, Leaving only one number after the decimal point, Then you have come to the right post.
Step-by-step explanation:
Round off to nearest 10. Rounding every place-value of number. Round off a number to the nearest tens round off to the nearest multiple of ten.
A large number may be rounded off to the nearest 10.
Hope It Helps!
Please help me with this question!! I also need the steps
Hi there!
[tex]\large\boxed{x = \frac{\pi}{3} \text{ and } \pi}[/tex]
We are given:
cos(7x)cos(4x) = -1 - sin(7x)sin(4x)
Begin by moving all terms with variables to one side:
cos(7x)cos(4x) + sin(7x)sin(4x) = -1
The corresponding trig identity is cos(A - B). Thus:
cos(7x - 4x) = cos(7x)cos(4x) + sin(7x)sin(4x) = -1
cos(3x) = -1
cos = -1 at π, so:
3x = π
x = π/3
We can also find another solution. Let 3π = -1:
3x = 3π
x = π
Thus, solutions on [0, 2π) are π/3 and π.
PLEASE SOMEONE HELP ME WITH THE MATH!!! It's on the picture!!!
N is to the left of the zero which means it is a negative number.
P is the the right of zero which means it is a positive number.
A negative number is less than a positive number, so the answer would be:
The number with the least value is N
The number with the greatest value is P

What is the equation of the line that has a slope of -3 and goes through the point (3, -1)?
Answer:
y = -3x + 8
Step-by-step explanation:
plug in the slope of -3 and the point (3, -1) into the equation: y = ax + b to find b. (the slope of -3 = a)
=> -1 = 3(-3) + b
=> b = 8
plug in b= 8 & the slope of -3 into the equation: y = ax + b
=> y = -3x + 8

A movie complex is showing the same movie in three theaters. In theater A, 44 of the 80 seats are taken. In theater B, 42 seats are taken and 28 seats are empty. In theater C, 27 of the 90 seats are empty. Which theater has the greatest percent of its seats taken? Which theater has the greatest of its seats taken ?
Answer:
Theater C
Step-by-step explanation:
Theater A has 80 seats, 44 of which are taken. 44/80 can be simplified to 11/20, which is 0.55 in decimal form, and 55% in percent form.
Theater B has 70 seats, because 42+28 = 70. 42 of those 70 seats are taken. 42/70 is 60%
Theater C has 90 seats, and because 27 are empty, we can subtract 27 from 90, which leaves us at 63 seats are taken. 63/70 is 70%
70% is the biggest percentage, so Theater C has the greatest seats taken.
I hope this helps! :))
Find the area of the shaded region
Answer:
Step-by-step explanation:
Area of the Shaded region = area of the Trapezoid - Area of the triangle
Area of the Trapezoid
b1 = 14
b2 = 26
h = 15
Area = (b1 + b2 ) * h / 2
Area = (14 + 26) * 15/2
Area = 40 * 15/2
Area = 300 in^2
Area of the triangle
Area = 1/2 b * h
b = 26
h = 15 - 6
h = 9
Area = 1/2 * 26 * 9
Area = 117 in^2
Area of the shaded region
Area of the shaded region = 300 - 117
Area of shaded region = 183

Answer:
QPN and RSU
Step-by-step explanation:
I need the value of Y
9514 1404 393
Answer:
y = 6
Step-by-step explanation:
Let's call the marked angles A, B, C, clockwise from upper left.
Along the vertical transversal, we observe that A+90° and C are alternate exterior angles, so are congruent. This lets us find a value for x.
A+90 = C
4x +90 = 11x -8
98 = 7x
14 = x
Then angle A is ...
A = 4x° = 4(14)° = 56°
__
Along the horizontal transversal, we observe that A and B are alternate exterior angles, so are congruent. This lets us find a value for y.
A = B
56° = (9y +2)°
54 = 9y
6 = y
The value of y is 6.
A car travels 30 1/5 miles in 2/3 of an hour what is the average speed in miles per hour of the ca A car travels 30 1/5 miles in 2/3 of an hour what is the average speed in miles per hour of the car
Answer:
45.3 miles/h
Step-by-step explanation:
let 'x' be the speed of the car.
60 × 2/3 = 120/3 = 40
30 × 1/5 = 151/5
151/5 /40 = x / 60
151 / 200 = x / 60
=> x = (151×60) / 200
=> x = 45.3

Answer:
∠GHJ and ∠FEC
Step-by-step explanation:
Alternate exterior angles are two angles that lie on the outer part of the parallel lines but on different sides.
∠GHJ and ∠FEC lie on the outer parts of the parallel lines, but different sides.
∠GHJ is on the lower left side.
∠FEC is on the upper right side.

. Duke's photography pays $9 for a 5x7 photograph.
If the photograph is sold for $15, what is the
percent of markup based on cost?
Answer:
the markup percentage is 66.67%
Step-by-step explanation:
The computation of the percent of markup based on cost is shown below:
= (Selling price - paid price) ÷ (paid price)
= ($15 - $9) ÷ ($9)
= 66.67%
By taking the difference of the selling price & paid price and then divided it by paid price we can get the percentage of markup
Hence, the markup percentage is 66.67%
The amount of a radioactive isotope decays in half every year. The amount of the isotope can be modeled by f(x) = 346(one half)x and f(1) = 173. What does the 173 represent?
9514 1404 393
Answer:
f(1) = 173 = the amount remaining after 1 year
Step-by-step explanation:
The function definition tells you f(x) is the amount of the isotope remaining after x years. Then ...
f(1) = 173 = the amount remaining after 1 year
__
(no units are given, so we don't know if that is 173 nanograms, or 173 truck loads)

Which of the following could be a function with zeros of —3 and 2? А f(x) = (x - 3)(x + 2) B f(x) = (x = 3)(x - 2) © f(x) = (x+3)(x - 2) D f(x) = (x+3)(x + 2)
Answer:
C
Step-by-step explanation:
to find the zeros you look at what value you would fill in for x to make zero, so (x+3) would have a zero of -3 and (x-2) would have a zero of 2
You deposit $2000 in an account that pays 7% interest compounded semiannually. After 5 years, the interest rate is increased to 7.28% compounded quarterly. What will be the value of the account after a total of 10 years?
The value of the account will be $_____. (Round to the nearest dollar as needed.)
9514 1404 393
Answer:
$4047
Step-by-step explanation:
For an interest rate r compounded n times per year for t years, the effective multiplier is ...
(1 +r/n)^(nt)
The multiplier for the first 5 years is ...
(1 +0.07/2)^(2·5) = 1.41059876
The multiplier for the last 5 years is ...
(1 +0.0728/4)^(4·5) = 1.43437218
Then the account value at the end of 10 years is ...
$2000(1.41059876)(1.43437218) ≈ $4047 . . . . balance after 10 years
