Answer:

Step-by-step explanation:

When is it appropriate to use the paired t test (involving the mean of the differences)? A. When two independent samples are compared. B. When two dependent samples are compared. C. When four samples are compared at once. D. When any two samples are compared.

Answers

Answer:

B. Two dependent samples are compared

Step-by-step explanation:

We use it when we are comparing Two dependent samples. The paired t-test can be likened to the repeated measures ANOVA test. Both of these two test are useful when comparing how a static group does in different test conditions.

But the difference between these two are:

We use the paired t-test if the explanatory variable has two levels.

While the Repeated measures ANOVA is used when the explanatory variable has greater than two levels.

A rectangular bedroom is 3 ft longer than it is wide. Its area is 270 ft2. What is the width of the room?

Step-by-step explanation:

Given

Hypotenuse (h) = 7

base (b) = 4

perpendicular (p) =?

Using Pythagoras theorem we get,

p = √h² - b²

= √7² - 4²

= √33

= 5.74

Hope it will help :)❤

p = a

a = 5.74 or u can write

a = √33

Answer:

5.74

Step-by-step explanation:

a=?

b=4

c=7

a^2=c^2-b^2

=7^2-4^2

Answer:

[tex](15s)^6[/tex] is the same as [tex]15^6[/tex] × [tex]s^6[/tex]

The above statement can be proven by a rule related to exponents that states: [tex](ab)^c = a^c[/tex] × [tex]b^c[/tex]

[tex]3s^4[/tex] × [tex]5s^2[/tex] = [tex]15s^6[/tex]

(Work for the equation above ---> You would multiply the 3 and 5 together (3 x 5 = 15) and then multiply the s terms together [tex]s^4[/tex] x [tex]s^2[/tex] , and this can be done using the exponent rule --> [tex]a^b[/tex] x [tex]a^c[/tex] = [tex]a^{b+c}[/tex]. This means that [tex]s^4[/tex] x [tex]s^2 = s^{4+2} = s^6[/tex]) This results in [tex]15s^6[/tex]

[tex]15s^6 \neq 15^6[/tex] x [tex]s^6[/tex]

f(x, y) = 2x² + 3y² + 4

Answers

Answer:

Step-by-step explanation:

f(x,y)=2x2+3y2−4x−1 ⇒ ∇f =⟨4x−4,6y⟩=⟨0,0⟩ ⇒ x=1, y = 0. Thus (1,0) is the only critical point of f, and it lies in the region x2+y2<16.Ontheboundary,g(x,y)=x2+y2=16 ⇒ λ∇g=⟨2λx,2λy⟩,so6y=2λy ⇒ eithery=0orλ=3. Ify=0,then x=±4;ifλ=3,then4x−4=2λx ⇒ x=−2andy=±2√3. Now f(1,0) = −3, f(4,0) = 15, f(−4,0) = 47, and f−2,±2√3 = 51. Thus the maximum value of f(x,y) on the disk x2+y2 ≤ 16 is f−2,±2√3 = 51, and the minimum value is f (1, 0) = −3.
