A bag contains five yellow tickets numbered one to five. The bag also contains five green tickets numbered one to five. You rand
tamaranim1 [39]

The probability of picking a ticket that is green or has a number greater than four is 3/5

<h3>How to determine the probability?</h3>

The given parameters are:

Yellow = 1 - 5

Green = 1 - 5

Total = 10

There are 2 cards whose numbers are greater than 4 i.e. Yellow 5 and Green 5

So, we have:

P(Number greater than 4) = 2/10

There are 5 green cards.

So, we have:

P(Green) = 5/10

Also, 1 green card is numbered greater than 4

So, we have:

P(Green greater than 4) = 1/10

The required probability is:

P = P(Green) + P(Number greater than 4) - P(Green greater than 4)

This gives

P = 5/10 + 2/10 - 1/10

Evaluate

P = 6/10

Simplify

P =3/5

Hence, the probability of picking a ticket that is green or has a number greater than four is 3/5

The value of y from the diagram is 9

<h3>Similar shapes</h3>

From the given figure, the shapes are similar, using the similarity theorem of triangles, you ill have;

6/10 = y/15

Cross multiply

10y = 15* 10

10y = 90

y = 90/10

y = 9

Hence the value of y from the diagram is 9

According to records in a large hospital, the birth weights of newborns have a symmetric and bell-shaped relative frequency dist
Kamila [148]

Answer:

15.9% of babies are born with birth weight under 6.3 pounds.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 6.8 pounds

Standard Deviation, σ = 0.5

We are given that the distribution of  birth weights is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(birth weight under 6.3 pounds)

P(x < 6.3)

P( x < 6.3) = P( z < \displaystyle\frac{6.3 - 6.8}{0.5}) = P(z < -1)

Calculation the value from standard normal z table, we have,  

P(x < -1) = 0.159 = 15.9\%

15.9% of babies are born with birth weight under 6.3 pounds.
