Answer:

yeah here I's the answer

Step-by-step explanation:

Weights of adult males are normally distributed with a mean of u = 85.5 kg and a standard deviation of o= 17.7 kg. If a sample yields x = 80 kg, how many standard deviations is this away from the mean? What is the probability that another sample of size is n=1000 has mean < 80kg? (Hint: Use the Central Limit Theorem.)

Emily brought $35 to the fair. At the fair, she spent $16 on ride tickets and she also bought lunch. She had $7 when she left th

MatroZZZ [7]

Answer:

Emily spend $12 on lunch.

The correct option is Option A i.e 23 plus x equals 35; x equals 12

Step-by-step explanation:

Let amount spent on Lunch = x

Total money Emily brought to the fair = $35

Money Spend on ride tickets and lunch = 16+x

Money Left with Emily = $ 7

We need to find how much Emily spend on lunch

SO,

We can write the equation $16+x+7=35\\$

As, total money is 35 and $7 are still with emily

Solving to find value of x

$16+x+7=35\\x+23=35\\x=35-23\\x=12$

So, Emily spend $12 on lunch.

The correct option is Option A i.e 23 plus x equals 35; x equals 12

Discuss the validity of the following statement. If the statement is always true, explain why. If not, give a counterexample.

Zigmanuir [339]

Answer:

$P(E \cup F)=P(E)+P(F)$ .

Step-by-step explanation:

Given the statement

If $P(E)+P(F)=P(E \cup F)+P(E \cap F)$ , then E and F are mutually exclusive events.

If two events are mutually exclusive, they have no elements in common. Thus, P(E∩F)=0.

Therefore, the statement is always true as P(E∩F)=0

For mutually exclusive events:

$P(E \cup F)=P(E)+P(F)$ .
