Answer:

t = r n − 2 1 − r 2 = 0.45 25 − 2 1 − 0.45 2 = 2.417 The critical value for α = 0.05 for a two-tailed test using the t 24 distribution is 2.064. Your value is greater than this, so you reject the null hypothesis and conclude that the study produced evidence that the variables are significantly correlated

Sergeeva-Olga [200]

f(x) = 5

g(x) = \sqrt{x + 2}

(f-g)(x) = 5 -  \sqrt{x + 2}

(f * g)(x) = 5(\sqrt{x + 2}) = 5\sqrt{x + 2}

(f/g)(x) = \frac{5}{\sqrt{x + 2}} = \frac{5\sqrt{x + 2}}{{x + 2}}

f(g(x)) = 5

just olya [345]

Answer:

3

Step-by-step explanation:

Key Word: 12 servings for every 5 people. if she makes it to hold 8 servings, what is enough plans she needs to feed 10 people?

formula: so 12 for 5 then 24 for 10.

solving problem:

12 people over 5 people = x over 10 people

since 5 times 2 equals 10 then 12 times is 24.. so we need 24 servings

we know from reading the question that each pan makes 8 servings.

\frac{24}{8} = 3

Explain how to solve 3^x-4=6 using the change of base formula log base b of y equals log y over log b. include the solution for
Alexxandr [17]

Answer:

x = log 10/log 3

Step-by-step explanation:

3^x - 4 = 6

3^x = 10

We take log base 3 of both sides since log_3 3^x is simply x.

log_3 3^x = log_3 10

x = log_3 10

We have an answer for x, but it is a log base 3. We want log base 10.

Now we use the change of base formula.

log_b y = log y/log b

x = log 10/log 3

Find the Area of the figure below, composed of a parallelogram and two semicircles. Round to the nearest tenths place.
Eva8 [605]

Answer:

100.3 square units

Step-by-step explanation:

Area of the composite figure = area of parallelogram + area of circle

Note: 2 semicircles = 1 full circle

Area of the figure = a*h + πr²

Where,

a = 10

h = 5

r = ½ of 8 = 4

Plug in the value into the equation

Area = 10*5 + π*4²

Area = 50 + π*16

Area = 100.265482 ≈ 100.3 square units (nearest tenth)
