Answer:
<h2>1) C. 8x + 2x = 10x</h2><h2>2) z = 5</h2><h2>3) y = 10</h2><h2>4) x = 1/2</h2><h2>5) x = 17</h2><h2>6) C. 1/4x + 4 = 3</h2><h2>
Step-by-step explanation:</h2>
<h3>1. <u>C. 8x + 2x = 10x</u></h3><h3 /><h3>2. 3z - 2 = 13</h3><h3>3z = 13 + 2</h3><h3>3z = 15</h3><h3><u>z = 5</u></h3><h3 /><h3>3. -5y - 10 = -60</h3><h3>-5y = -60 + 10</h3><h3>-5y = -50</h3><h3><u>y = 10</u></h3><h3 /><h3>4. 4x - 5 + 2x = -2</h3><h3>4x + 2x = -2 + 5</h3><h3>6x = 3</h3><h3><u>x = 1/2</u></h3><h3 /><h3>5. x - 8/3 = 3</h3><h3>x - 8 = 9</h3><h3>x = 9 + 8</h3><h3><u>x = 17</u></h3><h3 /><h3>6. <u>C. 1/4x + 4 = 3</u></h3><h3>(1/4 × -4/1) + 4 = 3</h3><h3>-1 + 4 = 3</h3><h3 />
The two triangles are similar all angles are equal.
the sides are proportional
10/22 = AQ/AQ + 18
22AQ = 10 AQ+ 180
12 AQ = 180
AQ = 15
It's already in scientific notation form;
Answer of your question,
3x+46 = 10x-80
7x = 34
x = 4.85
Yes. Parenthesis first, then if any exponents, then multiplication or division, then addition and subtraction. PEMDAS.
Answer:
C) If the null hypothesis were true, there is a 2 percent chance of obtaining a chi-square value of at least 7.82.
Step-by-step explanation:
The value of the chi-square test statistic was 7.82 and the p- value is 0.02. This means that if the null hypothesis were true there is a 2 percent chance of obtaining a chi square value of at least 7.82
The p- value is defined as obtaining the test statistic under H0 as extreme as observed.
When the p- value is less than 0.05 in the chi square goodness fit test it means that the null hypothesis is rejected.
There fore option C is the best answer.
A)There is a 2 percent chance that the company's claim is correct.
B) There is a 2 percent chance of obtaining a chi-square value of at least 7.82.
C) If the null hypothesis were true, there is a 2 percent chance of obtaining a chi-square value of at least 7.82.
D) If the null hypothesis were true, there is a 2 percent chance that the company's claim is correct.
E) If the null hypothesis were true, there is a 2 percent chance of obtaining a chi-square value of 7.82.
