Suppose P(E) = 0.3. Find P(not E). Suppose P(not E) = 65%. Find P(E).

larisa [96]

Try this option:
1. rule: P(E)+P(not E)=1.
2. according to the rule above
P(not E)=1-P(E)=1-0.3=0.7;
P(E)=1-P(not E)=(100-65)%=35%.

You have 12 1/3 yards and you need 47 yards how many more yards of fabric do you need

Lady bird [3.3K]

Answer:

34 2/3

Step-by-step explanation:

You need 47 yards. You have 12 1/3

47 - 12 1/3. So we'll break it down.

47 - 12 = 35.

Now, 35 + 12 1/3 would make 47 1/3

So now 35 - 1/3=34 2/3

34 2/3 + 12 1/3 = 47

Kilo typed 1,125 words in 15 minutes let w represent the number of words typed each minute If Lolo typed the same number of word

Alborosie

Answer:

She type 75 words in 1 minute.

Step-by-step explanation:

Given:

Lolo typed 1,125 words in 15 minutes.

Let w represent the number of words typed each minute.

Now, to find the number of words she type in 1 minute if Lolo typed the same number of words each minute.

So, we solve it by using cross multiplication method:

As 1125 words is equivalent to 15 minutes.

Thus, w number of words equivalent to 1 minutes.

$\frac{1125}{15} =\frac{w}{1}$

By cross multiplying we get:

⇒ $1125=15w$

Dividing both sides by 15 we get:

⇒ $75=w$

⇒ $w=75.$

Therefore, she type 75 words in 1 minute.

A scientist is studying the growth of a particular species of plant. He writes the following equation to show the height of the

gtnhenbr [62]

At day 0 the height of the plant = 12 cm

Calculate how many days to get to 16.13 cm:-
16.13 = 12(1.03)^n

1.03^n = 16.13 / 12 = 1.34417
n = ln 1.34417 / ln 1.03 = 10 days

I would think that a reasnable domain would be 0 =< n <= 100
