Answer: Hence, the probability of having no girls is 0.0313.

Step-by-step explanation:

Since we have given that

Number of children a family has = 5

Number of outcomes would be 2^5=32

Probability of having a girl = \dfrac{1}{2}=0.5

We need to find the probability of having no girls.

P(no girls ) = P( all boys )

So, it becomes,

P(all\ boys)=(0.5)^5=0.03125\approx 0.0313

Hence, the probability of having no girls is 0.0313.

use the ruler provided to measure the base of the parallelogram shown to the nearest 0.5 CM which measurement is the closest to
valkas [14]

Answer:

Area of the parallelogram = 21.6 cm²

Step-by-step explanation:

Area of a parallelogram = Base × Height of the side parallel to the base

By using ruler,

Base = 4.8 cm

Height of parallelogram = 4.5 cm

Area of the parallelogram = 4.8 × 4.5

                                           = 21.6 cm²

A map has a scale of 1 in: 25 mi. Two cities are 175 mi apart. How far apart are they on the map?
myrzilka [38]
Ratio = 1/25
Let, the distance b/w cities on map = x

It would be: 1/25 = x/175
x = 175/25
x = 7

In short, Your Answer would be 7 in

Hope this helps!

A simple die is thrown 100 times and the number five appears 14 times. Find the experimental probability of throwing a five, giv
mario62 [17]

Answer:

The experimental probability of throwing a five is 0.087.

Step-by-step explanation:

Given:

Number of trials (n) = 100

Number of times 5 appears (x) = 14

Let the event of occurrence of 5 be success and the probability represented by 'p'. So, all the other numbers occurrence is failure and its probability is represented as 'q'.

Probability of success is given as:

p=\frac{Number\ of\ favorable\ events}{Total\ number\ of\ outcomes}

Favorable event is occurrence of 5. So, its number is 1 as there is only one 5 in the die. Total outcomes are 6 as there are six numbers. So,

p=\frac{1}{6}

Now, probability of failure is given by the formula:

q=1-p=1-\frac{1}{6}=\frac{5}{6}

Now in order to find the experimental probability of 14 successes out of 100 trials, we apply Bernoulli's theorem which is given as:

P(x) = ^nC_xp^xq^{n-x}

Plug in all the given values and find the probability of 14 successes. This gives,

P(x=14)=^{100}C_{14}(\frac{1}{6})^{14}(\frac{5}{6})^{100-14}\\\\P(x=14)=0.087

Therefore, the experimental probability of throwing a five is 0.087.
