Assuming you meant 2+3(67x34)=y
67x34=2278
2+3(2278)=y
5(2278) or 5x2278=y
y=11390

In a poll of 745 randomly selected adults, 591 said that it is morally wrong to not report all income on tax returns. Use a 0.01

Marianna [84]

Answer:

The calculated value Z = 2.734 > 2.576 at 0.01 level of significance

Null hypothesis is rejected

The claim that 75% of adults say that it is morally wrong to report all income on tax returns.

Step-by-step explanation:

Step(i):-

Given random sample size 'n' = 745

Given In a poll of 745 randomly selected adults, 591 said that it is morally wrong to not report all income on tax returns

sample proportion

$p^{-} = \frac{x}{n} = \frac{591}{745} = 0.7932$

Given Population proportion P = 0.75

Q = 1-P

Q = 1 - 0.75 = 0.25

Null Hypothesis :H₀: P=0.75

Alternative Hypothesis :H₁:P≠ 0.75

Step(ii):-

Test statistic

$Z = \frac{p^{-}-P }{\sqrt{\frac{P Q}{n} } }$

$Z = \frac{0.7932-0.75 }{\sqrt{\frac{0.75 X 0.25}{745} } }$

Z = 2.734

Level of significance ∝ = 0.01

The critical value Z =2.576

The calculated value Z = 2.734 > 2.576 at 0.01 level of significance

Null hypothesis is rejected

The claim that 75% of adults say that it is morally wrong to report all income on tax returns.

Find mzC. B (2x – 12) (9x – 26) (4x + 43)

MrMuchimi

Answer:

m<C = 119°

Step-by-step explanation:

Create an equation to find the value of x.

(9x - 26)° = (2x - 12)° + (4x + 43)° (exterior angle theorem of a ∆)

Solve for x

9x - 26 = 2x - 12 + 4x + 43

Add like terms

9x - 26 = 6x + 31

9x - 6x = 26 + 31

3x = 57

Divide both sides by 3

x = 19

✔️m<C = 4x + 43

Plug in the value of x

m<C = 4(19) + 43

m<C = 76 + 43

m<C = 119°

For the following system, use the second equation to make a substitution for y in the first equation. 3x + y = 2 y + 4 = 3x

expeople1 [14]

First, set the second equation with y as the isolated variable. To do this, subtract 4 from both sides to get
$y = 3x - 4$
Now that you know the value of y, put that expression in for y in the first equation to get
$3x + (3x - 4) = 2$
Then, simplify by adding the x terms together to get
$6x - 4 = 2$
add 4 on both sides to isolate the x terms to get
$6x = 6$

then divide 6 from both sides to get
$x = 1$
Using that x value, plug it into one of the equations as x to find y ( I will use y=3x-4)
$y = 3(1) - 4 = 3 - 4 = - 1$
x=1 and y=-1 is the answer
