Answer:
The error is in the second line.
x = -1
Step-by-step explanation:
When solving for "x", you are trying to isolate it, or move everything else to the other side. You may have learned that <em>"what you do to one side, you do to the other"</em> .
2x + 18 = 16
2x = 34 18 was added to the right side, but not to the other.
If you add 18 on both sides, then the equation would be:
2x + 36 = 34 "x" is not being isolated.
Instead, you should subtract 18 from 16.
<u>Correct solutions steps</u>:
2x + 18 = 16
2x + 18 - 18 = 16 - 18 Subtract 18 from both sides to cancel out 18
2x = -2
2x/2 = -2/2 Divide both sides by 2
x = -1 Final answer
Answer:
98.01% probability of getting 5 clean sheets
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, the order that the sheets are chosen is not important, so we use the combinations formula to solve this problem.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
0.4% of the sheets contain spots
Of 500, that is 0.004*500 = 2.
What is the probability of getting 5 clean sheets although 0.4% of the sheets contain spots?
Desired outcomes
2 are defective, so 5 sheets from a set of 500 - 2 = 498.
Total outcomes
5 sheets from a set of 500.
Probability:
98.01% probability of getting 5 clean sheets
Step-by-step explanation:
Hey, there!!
5(R+2)-6.
Fistly multiply (R+2) by 5.
=5R + 10 - 6
Subtract 6 from 10.
= 5R +4.
Therefore, 5R + 4 is correct answer.

A whole revolution is equal to 360°. The quadrants in the Cartesian plane is divided as such,
Quadrant I : 0° to 90°
Quadrant II: greater than 90° to 180°
Quadrant III: greater than 180° to 270°
Quadrant IV: greater than 270° to 360°
To answer the question above, we determine the remainder when we divide 570° by 360°.
570° ÷ 360° = 1 remainder 210
Since, the remainder is 210° the terminal side of the angle lies in Quadrant III.
