Mathematics
1 answer:
ra1l [238]3 years ago
8 0

Answer:

The value of the test statistic is z= -14.53

Step-by-step explanation:

Pcap= 0.3 ,p=0.5 ,q= 1-0.5= 0.5, n=1320

Z= (pcap- p) / √(p×q)/n

Z=( 0.3- 0.5) / √ (0.5 × 0.5)/1320

Z= -0.2/(√0.0001894)

Z= -14.53

What is the value of the expression shown below 10+(2x3)^2 divided by 4x (1/2)^3
stira [4]

Answer:

10 + (2 x 3)^2 / 4 x (1/2) ^3

First do the parentheses

2 x 3 = 6

1 / 2 = 0.5

We are left with

10 + 6^2 /4 x 0.5^3

Do exponents

6 x 6 = 36

0.5 x 0.5 x 0.5 = 0.125

10 + 36 / 4 x 0.125

Divide by 4 and multiply by 0.125

36 / 4 = 9

9 x 0.125 = 1.125

We are left with

10 + 1.125 = 11.125

The answer is 11.125

Step-by-step explanation:

what is the growth factor of y=34×4^x, the initial amount of y=15×3^x and the decay factor of y=17×0.2^x
11Alexandr11 [23.1K]
So the growth factor is the base of the exponential term, so the base of y = 34 * 4^x is 4.
the initial amount is the amount at x = 0
y = 15 * 3^xy = 15 * 3^0y = 15 * 1y = 15 is the initial amount
the decay factor of y=17×0.2^x is same as the growth factor, it is 0.2

Determine the product<br> (4.2x100). (5.7x100)
Tom [10]

Answer:

(4.2x100).(5.7x100) = 239.400

Step-by-step explanation:

We need to determine the product of (4.2x100).(5.7x100).

We know that when two numbers are multiplied together, the product is the same regardless of the order of the multiplicands. For that reason, we can multiply all together, and the result will be the same regardless of the order of the multiplicands:

Then:

(4.2x100).(5.7x100) = 4.2x100x5.7x100 = 420x570= 239.400
