Answer:

c tomato 2.5

pepper = 3.5

Step-by-step explanation:

Let t= the price of tomato plants

p =the price of pepper plants

3t+ 4p = 21.50

5t+ 2p = 19.50

Multiply the second equation by -2

-10t -4p =-39

Add this to the first equation to eliminate p

-10t -4p =-39

3t+ 4p = 21.50

---------------------

-7t = -17.5

Divide by -7

t = 2.5

Now find p

5t+ 2p = 19.50

5( 2.5) + 2p = 19.50

12.5+2p = 19.50

Subtract 12.5 from each side

2p =7

p =3.5

We want the price of 1 tomato and 1 p

3.5+2.5

Some sources report that the weights of full-term newborn babies in a certain town have a mean of 8 pounds and a standard devia

Elodia [21]

Answer:

0.682 is the probability that one newborn baby will have a weight within one standard deviation of the mean.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 8 pounds

Standard Deviation, σ = 0.6 pounds

We are given that the distribution of weights of full-term newborn babies is a bell shaped distribution that is a normal distribution.

Formula:

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

P(weight between 7.4 and 8.6 pounds)

$P(7.4 \leq x \leq 8.6) = P(\displaystyle\frac{7.4 - 8}{0.6} \leq z \leq \displaystyle\frac{8.6-8}{0.6}) = P(-1 \leq z \leq 1)\\\\= P(z \leq 1) - P(z < -1)\\= 0.841 - 0.159 = 0.682 = 68.2\%$

$P(7.4 \leq x \leq 8.6) = 6.82\%$

This could also be found with the empirical formula.

0.682 is the probability that one newborn baby will have a weight within 0.6 pounds of the mean.
