Trust me, its C. Associative (Associative property of multiplication)
[mark me brainliest please :( i need 3 more]
The property illustrated by the statement (3 x 6) * 4 = 3 x (6 x 4) is the Associative Property. So, the correct option is C. Associative.
The Associative Property states that the grouping of numbers being multiplied does not affect the result. In this case, it means that when multiplying three numbers, the order in which we group them does not change the final product. We can either multiply (3 x 6) first and then multiply by 4, or multiply 3 by (6 x 4) first and achieve the same result.
Therefore, the correct option is C. Associative.

Y=hx+s solve for the equation for h
Answer:
h=y/x
Step-by-step explanation:
Let's solve for h.
y=hx
Step 1: Flip the equation.
hx=y
Step 2: Divide both sides by x.
hx/x=y/x
h=y/x
Answer:
h = [tex]\frac{y - s}{x}[/tex]Step-by-step explanation:
Subtract s
Y - s = hx
divide by x
h = (y - s)/x

Evaluate the iterated integral 2 0 2 x sin(y2) dy dx. SOLUTION If we try to evaluate the integral as it stands, we are faced with the task of first evaluating sin(y2) dy. But it's impossible to do so in finite terms since sin(y2) dy is not an elementary function. So we must change the order of integration. This is accomplished by first expressing the given iterated integral as a double integral. Using this equation backward, we have 2 0 2 x sin(y2) dy dx
Answer:
Step-by-step explanation:
Given that:
[tex]\int^2_0 \int^2_x \ sin (y^2) \ dy dx \\ \\ \text{Using backward equation; we have:} \\ \\ \int^2_0\int^2_0 sin(y^2) \ dy \ dx = \int \int_o \ sin(y^2) \ dA \\ \\ where; \\ \\ D= \Big\{ (x,y) | }0 \le x \le 2, x \le y \le 2 \Big\}[/tex]
[tex]\text{Sketching this region; the alternative description of D is:} \\ D= \Big\{ (x,y) | }0 \le y \le 2, 0 \le x \le y \Big\}[/tex]
[tex]\text{Now, above equation gives room for double integral in reverse order;}[/tex]
[tex]\int^2_0 \int^2_0 \ sin (y^2) dy dx = \int \int _o \ sin (y^2) \ dA \\ \\ = \int^2_o \int^y_o \ sin (y^2) \ dx \ dy \\ \\ = \int^2_o \Big [x sin (y^2) \Big] ^{x=y}_{x=o} \ dy \\ \\= \int^2_0 ( y -0) \ sin (y^2) \ dy \\ \\ = \int^2_0 y \ sin (y^2) \ dy \\ \\ y^2 = U \\ \\ 2y \ dy = du \\ \\ = \dfrac{1}{2} \int ^2 _ 0 \ sin (U) \ du \\ \\ = - \dfrac{1}{2} \Big [cos \ U \Big]^2_o \\ \\ = - \dfrac{1}{2} \Big [cos \ (y^2) \Big]^2_o \\ \\ = - \dfrac{1}{2} cos (4) + \dfrac{1}{2} cos (0) \\ \\[/tex]
[tex]= - \dfrac{1}{2} cos (4) + \dfrac{1}{2} (1) \\ \\ = \dfrac{1}{2}\Big [1- cos (4) \Big] \\ \\ = \mathbf{0.82682}[/tex]

Answer: The answer is B
Step-by-step explanation:
A group of doctors published an article in the New England Journal of Medicine. In the article they revealed the findings of a study to determine if there is a difference in survival rates for men who undergo surgery for localized prostate cancer and those who are treated with observation only. The researchers randomly assigned 731 men with localized prostate cancer to radical prostatectomy or observation. During the years of follow-up, 245 of 367 (66.8%) assigned to surgery survived for at least 5 years and 223 of 364 men (61.3%) assigned to observation survived for at least 5 years.
Required:
a. Construct and interpret a 99% confidence interval for the difference in the true proportion of men like these that would survive for at least 5 years after receiving surgery and the proportion that would survive for at least 5 years when only being observed.
b. How does the confidence interval from part a tell you that there is not sufficient evidence at the a=.01 level that there is a difference in the proportion of men with localized prostate cancer who survive at least five years after receiving surgery and the proportion of men with localized prostate cancer who survive at least five years when only being observed. In other words, how would you know that the p-value for a 2 proportion z test would not be significant at the 0.01 level?
Answer:
a) CI = ( - 0,0352 ; 0,1472 )
b) The CI include 0 since that means we don´t have sufficient evidence at α = 1 % to support differences between the two proportions
Step-by-step explanation:
From sample 1. ( assigned to surgery)
sample size n = 367
sample proportion p₁ = 245/367 p₁ = 66,8 % or p₁ = 0,668
Then q₁ = 1 - 0,668 q₁ = 0,332
From sample 2. ( assigned to observation )
sample size n₂ = 364
sample proportion p₂ = 223/364 p₂ = 61,2 % or p₂ = 0,612
Then q₂ = 1 - 0,612 q₁ = 0,388
Test Hypothesis is:
Null hypothesis H₀ p₂ = p₁
Alternative Hypothesis Hₐ p₂ ≠ p₁
a) CI ( 99 %) if CI = 99% significance level α = 1 % α = 0,01
α/2 = 0,005 n z-table we look z (c) for 0,005
z(c) = 2,578
CI = ( p₁ - p₂ ) ± z(α/2) √(p₁*q₁) / n₁] + [ p₂*q₂/n₂
CI =(0,668 -0,612 ) ± 2,578 * √(0,668*0,332) /367 + (0,612*0,388)/364
CI = 0,056 ± 2,578*√6,04 *10⁻⁴ + 6,52 *10⁻⁴
CI = 0,056 ± 2,578*3,54*10⁻²
CI = ( 0,056 - 0,0912 ; 0,056 + 0,0912 )
CI = ( - 0,0352 ; 0,1472 )
b) The CI include 0 since that means we don´t have sufficient evidence at α = 1 % to support differences between the two proportions

HELP ASAP!!!!! Solve for x and y. Round your answers to the nearest tenth.
Answer:
x = 9.4 and y = 8
Step-by-step explanation
If you're using a calculator to solve this, make sure it's in Degree mode.
Solve for x:
Sin(32) =[tex]\frac{opp}{hyp}[/tex] = [tex]\frac{5}{x}[/tex]
bring x to one side
x = [tex]\frac{5}{sin(32)}[/tex] = 9.4
Solve for y:
Tan(32) = [tex]\frac{opp}{adj}[/tex] = [tex]\frac{5}{y}[/tex]
bring y to one side
y = [tex]\frac{5}{tan(32)}[/tex] = 8

What did I forget to do in this question? What should the answer be?
Use only Quadratic Formula
[tex] {7x}^{2} + 9x + 2 = 0[/tex]
[tex] {x}^{2} + 9x + 14 = 0[/tex]
[tex](x + 7)(x + 2) = 0[/tex]
x= -7,x=-2
The mistake is in the first step. You seem to want to divide through by 7, but you only did it correctly with the x ² term. What you should have after doing this is
7x ² + 9x + 2 = 0
→ x ² + 9/7 x + 2/7 = 0
This step isn't actually necessary to begin with since the starting quadratic is easily factorized:
7x ² + 9x + 2 = (7x + 2) (x + 1) = 0
Then
7x + 2 = 0 or x + 1 = 0
7x = -2 or x = -1
x = -2/7 or x = -1
