Answer:

x = 110°

Step-by-step explanation:

∠ QRS = ∠ YRT = 110° ( vertically opposite angles )

∠ PQR = 180° - 120° = 60° ( adjacent angles )

The sum of the interior angles of a quadrilateral = 360°

Sum the angles and equate to 360°, that is

110 + 60 + x + 80 = 360

250° + x = 360° ( subtract 250° from both sides )

x = 110°

Joe wants to buy a skateboard but he doesn't know if he has enough money. The price of the skateboard is $85 and the sales tax i
Orlov [11]

Answer:

<h2> The skateboard has a total cost of $90.10</h2>

Step-by-step explanation:

Givens

  • The skateboard costs $85.
  • The sales tax is 6%.

The total cost of the skateboard would be $85 plus the sales tax, like the following expression shows

85+0.06(85)=85+5.1=90.1

Therefore, the skateboard has a total cost of $90.10, which includes sales tax.

The Ohio Department of Agriculture tested 203 fuel samples across the state in 1999 for accuracy of the reported octane level. F
OlgaM077 [116]

Answer:

The Sample size is 1918.89035

Step-by-step explanation:

Consider the provided information.

It is given that 14 out of 105 samples failed.

Therefore p = 14/105 = 0.13 3... and q=1-0.133=0.867

Samples would be needed to create a 99 percent confidence interval.

Subtract the confidence level from 1, then divide by two.

\frac{(1 -0.99)}{2}=0.005

By standard normal table z=2.5758≈2.58

Calculate the sample size as:

n=\frac{z^2pq}{e^2}

Where,  e is the margin of error,

Substitute the respective values.

n=\frac{(2.58)^2(0.133)(0.867)}{(0.02)^2}=1918.89

Hence, the Sample size is 1918.89035

A line passes through (2,8) and (4,12). Which equation Best represents the line
SVETLANKA909090 [29]

Answer:

y = 2x + 4

Step-by-step explanation:

First, find the <em>rate</em> <em>of change</em><em> </em>[<em>slope</em>], <em>m</em><em> </em><em>=</em><em> </em><em>-</em><em>y</em><em>₁</em><em> </em><em>+</em><em> </em><em>y</em><em>₂</em><em>\</em><em>-</em><em>x</em><em>₁</em><em> </em><em>+</em><em> </em><em>x</em><em>₂</em><em>.</em><em> </em>Next, you do either\or:

12 = 2(4) + b; 4 = b

8 = 2(2) + b; 4 = b

No matter which ordered pair you use, you will ALWAYS get the same answer, IF you put them in their correct places.

I am joyous to assist you anytime.
