Crazy boy [7]
All together is - 60 cupcakes

Jim placed - 0.45 or 5 cupcakes

Dora placed - 10

Ada placed - 25% or 15 

Kim placed the remaining and that is - 30 

10 + 5 = 15 and 15 + 15 = 30 so Kim had 30 that means 30 + 30 = 60 cupcakes

A sample of 100 is drawn from a population with a proportion equal to 0.50. Determine the probability of observing between 43 an
diamong [38]

Answer:

The probability of observing between 43 and 64 successes=0.93132

Step-by-step explanation:

We are given that

n=100

p=0.50

We have to find the probability of observing between 43 and 64 successes.

Let X be the random variable  which represent the success of population.

It follows binomial distribution .

Therefore,

Mean,\mu=np=100\times 0.50=50

Standard deviation , \sigma=\sqrt{np(1-p)}

\sigma=\sqrt{100\times 0.50(1-0.50)]

\sigma=5

Now,

P(43\leq x\leq 64)=P(42.5\leq x\leq 64.5)

P(42.5\leq x\leq 64.5)=P(\frac{42.5-50}{5}\leq Z\leq \frac{64.5-50}{5})

=P(-1.5\leq Z\leq 2.9)

P(42.5\leq x\leq 64.5)=P(Z\leq 2.9)-P(Z\leq- 1.5)

P(42.5\leq x\leq 64.5)=0.99813-0.06681

P(43\leq x\leq 64)=0.93132

Hence, the probability of observing between 43 and 64 successes=0.93132

If line segment ab=7cm draw a perpendicular at a point c on line ab such the ac=3.5cm
Reil [10]

See attachment for the drawing of the perpendicular at a point c on line ab such the ac = 3.5 cm

<h3>How to draw the perpendicular at a point c on line ab such the ac = 3.5 cm?</h3>

The given parameters are:

Length of segment AB = 7 cm

Also, we have:

Point C is located on line segment AB

This means that:

Length of segment AC = Length of segment BC = 3.5 cm

When represented on a line segment, we have:

A          C          B

See attachment for the drawing of the perpendicular at a point c on line ab such the ac = 3.5 cm
