The answer is D. 3+3=6*2=12+3=15*2=30...

The sequence is: 3 , 12 , 30 , 66

12-3 = 9
30-12 = 18
66-30 = 36

18/9 = 2
36/18 = 2

Because the difference of 2 of the numbers divided by the difference of the other 2 numbers is equal to 2, on of the steps is multiplying the previous number by 2,
But since the previous number multiplied by 2 does not equal the next number, the other step needed is to add 3 first.

The answer is 4) add 3, multiply by 2

5) Using the terms "input" and "output" and the definition of a function, explain why this relationship is or is

Aleks [24]

Answer:

This relationship is a function

Step-by-step explanation:

While a function may not have two output values (y) assigned to the same input value (x), it may have two input values (x) assigned to the output value (y).

The table follows that rule

A total of h males and (h - 2) females visit the museum on a certain day. If total of visitors for that day is 80, what is the v

Akimi4 [234]

Given:

Number of males = h

Number of females = (h-2)

Total number of visitors = 80

To find:

The value of h.

Solution:

We have,

Number of males = h

Number of females = (h-2)

So, the total number of visitors is:

$Total=h+(h-2)$

$Total=2h-2$

It is given that the total number of visitors is 80. So,

$2h-2=80$

$2h=80+2$

$2h=82$

Divide both sides by 2.

$h=\dfrac{82}{2}$

$h=41$

Therefore, the correct option is D.

Because of variability in the manufacturing process, the actual yielding point of a sample of mild steel subjected to increasing

photoshop1234 [79]

Answer:

P-value ≈ 0.3463

Step-by-step explanation:

Hypothesis test would be

$H_{0}$ :p=0.20

$H_{a}$ :p>0.20

We need to calculate the z-score of sample proportion and then the corresponding P-value.

z-score can be calculated as:

z= $\frac{p(s)-p}{\sqrt{\frac{p*(1-p)}{N} } }$ where

p(s) is the sample proportion of specimens yield before the theoretical point ( $\frac{9}{40}=0.225$ )

p is the proportion assumed under null hypothesis. (0.20)

N is the sample size (40)

Using the numbers

z= $\frac{0.225-0.2}{\sqrt{\frac{0.2*0.8}{40} } }$ =0.3953

and the P-value is then P(z)≈0.3463
