Answer: The larger number is 42

Step-by-step explanation:

Let X be the smaller number and Y be the larger number.

According to the question , we have the following equations :

2X+8=Y.................(1)\\\\Y-X=25.....(2)

Substitute the value of Y from (1) in equation (2), we get

2X+8-X=25\\\\\Rightarrow\ X=25-8\\\\\Rightarrow\ X=17

Substitute X=17 in equation (1) , we get

Y=2(17)+8=42

Hence, the larger number is 42.

X=2•y+8
|X-y|=25

2Y+8-Y=25
Y=25-8=17
25+17=42

So the numbers are 17 and 42; and the larger number is 42

The largest z-score available in most tables is 2.99, which corresponds to a probability of 99.86%. A fair coin is
lana66690 [7]

Answer:

The number of heads observed is 121.14 heads

Step-by-step explanation:

The formula for the z-score of a proportion is given as follows;

z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{pq}{n}}}

Where:

{\hat{p} = Sample proportion

p = Population success proportion = 0.5

q = 1 - p = 1 - 0.5 = 0.5

n = Number in of observation = 200

z = 2.99

Hence, we have;

z=\dfrac{\hat{p}-0.5}{\sqrt{\dfrac{0.5 \times 0.5}{200}}} = 2.99

Therefore;

{\hat{p}-0.5}{} = 2.99 \times \sqrt{\dfrac{0.5 \times 0.5}{200}} = 2.99 \times\dfrac{\sqrt{2} }{40}

{\hat{p} = 0.6057

Whereby \ \hat p = \dfrac{Number \ of \ heads}{Number \ of \ observation} =  \dfrac{Number \ of \ heads}{200} = 0.6057

∴ The number of heads observed = 200 × 0.6057 = 121.14 heads.
