Mathematics
1 answer:
Troyanec [42]3 years ago
7 0

Answer:

\large\boxed{m\angle R\approx76^o}

Step-by-step explanation:

\dfrac{\sin R}{SQ}=\dfrac{\sin S}{RQ}\\\\\text{We have:}\\\\SQ=32,\ RQ=26,\ S=52^o\to\sin52^o\approx0.788\\\\\text{Substitute:}\\\\\dfrac{\sin R}{32}=\dfrac{0.788}{26}\qquad\text{multiply both sides by 32}\\\\\sin R\approx0.97\to R=\arcsin(0.97)\\\\R\approx76^o

The inequality written in interval notation is therefore -4<x<-1  or (-4, -1)

<h3 /><h3>What are inequalities?</h3>

Inequalities are expressions separated by the mathematical inequalities ≤, ≥, < and >

For instance a < b is a form of inequality.

<h3>What is a number line?</h3>

A number line is a line on which numbers are marked at intervals, used to illustrate simple numerical operations.

From the given number line, we can see that closed circles are on -4 and -1. The inequality written in interval notation is therefore -4<x<-1  or (-4, -1)

Simplify the product using the distributive property. (-4h +2)(3h +7)
Alekssandra [29.7K]

Answer:

  A.  -12h² - 22h + 14

Step-by-step explanation:

(-4h +2)(3h +7) = -4h(3h +7) +2(3h +7) . . . . . . . (a +b)c = ac +bc

  = (-4h)(3h) + (-4h)(7) + (2)(3h) + (2)(7) . . . . . . . a(b +c) = ab +ac . . . (twice)

  = -12h² -28h +6h +14

  = -12h² -22h +14 . . . . . . . . collect terms

Lady_Fox [76]

Answer: 669

Step-by-step explanation:

Given, In a Gallup poll of randomly selected​ adults, 66% said that they worry about identity theft.

i.e. The proportion of adults said that they worry about identity theft. (p) = 0.66

Sample size : n= 1013

Then , Mean for the sampling distribution of sample proportion  = <em>np</em>

= (1013) × (0.66)

= 668.58 ≈ 669  [Round to the nearest whole number]

Hence, the mean of those who do not worry about identify theft is closest to​ 669 .
