Bess [88]

Lets look at the info we have:-

23 orders for Pepsi.
15 orders for mountain dew.

Question:-
How many more orders have there been for Pepsi than for Mountain Dew?

To answer this we will subtract the amount of Pepsi's ordered by the amount of Mountain Dew's ordered. The answer will be the amount of more Pepsi's ordered than the Mountain Dew's.

23 - 15 = 8
8 more Pepsi's were sold than Mountain Dew's.

CHECK OUR WORK:-

15 + 8 = 23
We were RIGHT!!!

So, 8 more Pepsi's were ordered than Mountain Dew's.

Hope I helped ya!1 xD

Suppose the odds against winning the lottery as 48,000,000 to 1. What is the probability of the event of winning the lottery giv

kupik [55]

The probability according to the given scenario will be " $\frac{1}{48,000,001}$ ".

According to the question:

The odds against winning the lottery are 48,000,000 to 1.
Favorable outcome = 1

→ The total outcome will be:

= $48,000,000 +1$

= $48,000,001$

As we know,

→ $P(E) = \frac{Favorable \ outcomes}{Total \ outcomes}$

By putting the values, we get

→ $=\frac{1}{48,000,001}$

Thus the above response is right.

A 7,5m ladder is placed with its lower end 2m away from the wall. How high up the wall does the ladder reach?

Dvinal [7]

Use the Pythagorean theorem:

Let x = the height.

2^2 + x^2 = 7.5^2

Simplify:

4 + x^2 = 56.25

Subtract 4 from both sides:

x^2 = 52.25

Take the square root of both sides:

x = 7.2284 m Round the answer as needed.

Illusion [34]

Answer:

The right answer is:

(a) 0.1456

(b) 18.125, 69.1202, 8.3139

Step-by-step explanation:

Given:

N = 24

n = 5

r = 7

The improperly drilled gearboxes "X".

then,

⇒ $P(X) = \frac{\binom{7}{x} \binom {17}{5-x}}{\binom{24}{5}}$

(a)

P (all gearboxes fit properly) = $P(x=0)$

= $\frac{\binom{7}{0} \binom{17}{5}}{\binom{24}{5}}$

= $0.1456$

(b)

According to the question,

$X = 91+5$

Mean will be:

⇒ $\mu = E(x)$

$=E(91+5)$

$=9E(1)+5$

$=9.\frac{nr}{N}+5$

$=9.\frac{5.7}{24} +5$

$=18.125$

Variance will be:

⇒ $\sigma^2=Var(X)$

$=V(9Y+5)$

$=81.V(Y)$

$=81.n.\frac{r}{N}.\frac{N-r}{N}.\frac{N-n}{N-1}$

$=81.5.\frac{7}{24}.\frac{24-7}{24}.\frac{24-5}{24-1}$

$=69.1202$

Standard deviation will be:

⇒ $\sigma = \sqrt{69.1202}$

$=8.3139$
