balu736 [363]

Answer: <em>Tara thinks correctly.</em>

Step-by-step explanation:

<em>Let's calculate the average value in sample A:</em>

<em>(4 × 70 + 5 × 100 + 6 × 125 + 7 × 135 + 8 × 70) ÷ 500 = 6,07 ≈ </em><em>6 hours</em>

<em>Let's calculate the average value in sample B:</em>

<em>(4 × 80 + 5 × 90 + 6 × 120 + 7 × 125 + 8 × 85) ÷ 500 = 6,09 ≈ </em><em>6 hours</em>

<em>So, Tara is correct in saying that the mean is 6.</em>

Computations For CC for Fraction defective

Sample No  d  p=d/100

1                    0       0

2                    0      0

3                    2     0.02

4                     1     0.01

5                     0      0

6                     1      0.01

7                     2      0.02

8                     0        0

                 Total   0.06

\overline{p} =\frac{1}{k}\sum p=\frac{0.06}{8} =0.0075

\overline{q} =1- 0.0075= 0.9925

3 sigma control limits for p chart are given by:

\overline{p} \pm 3\sqrt{\overline{p}\overline{q}/n}\Rightarrow 0.0075\pm 3\sqrt{\frac{0.0075*0.9925}{100}}

= 0.0075\pm0.0259\Rightarrow ( 0.0334,0 )

hence option e is correct

The graph shows the function f(x)=3^x
tangare [24]
The answer is D.
You have to make the whole numbers equal to then solve for the exponents:
F(x) means y, therefore, y is 9.
9 = 3^x.
3^2 is the same as 9.
Then, 3^2 = 3^x.
Then solve for the exponents,
2 = x
Therefore your answer is 2.

The difference between of two numbers is 9. If the large number is one more than twice the smaller number, find the larger numbe
sleet_krkn [62]

The larger number is 17

<em><u>Solution:</u></em>

Let "x" be the larger number

Let "y" be the smaller number

<em><u>The difference between of two numbers is 9</u></em>

Therefore,

larger number - smaller number = 9

x - y = 9 -------- eqn 1

<em><u>The large number is one more than twice the smaller number</u></em>

Larger number = 1 + 2(smaller number)

x = 1 + 2y ------ eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

<em><u>Substitute eqn 2 in eqn 1</u></em>

1 + 2y - y = 9

1 + y = 9

y = 9 - 1

y = 8

<em><u>Substitute y = 8 in eqn 1</u></em>

x - 8 = 9

x = 8 + 9

x = 17

Thus the larger number is 17
