Hi There!

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

Solution:

a = anna

d = dasha

a + 39 = d * 4

We can say that:

a = 1

d = 10

1 + 39 = 10 * 4

40 = 40

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

Answer:

Dasha had 10 rose bushes originally.

I hope this helps :)

Answer:

104

Step-by-step explanation:

Hello! :)

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

Dasha=d, Anna=a

d=4a

d-39=a+39

d=a+78

Plug in d as 4a:

4a=a+78

Solve for a:

3a=78

a=26

Because d=4a, plug in a:

d=4*26

d=104

Dasha originally have 104 rose bushes

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

I hope this helps :)

Normal Distribution. Cherry trees in a certain orchard have heights that are normally distributed with mu = 112 inches and sigma
Lubov Fominskaja [6]

Answer:

The probability that a randomly chosen tree is greater than 140 inches is 0.0228.

Step-by-step explanation:

Given : Cherry trees in a certain orchard have heights that are normally distributed with \mu = 112 inches and \sigma = 14 inches.

To find : What is the probability that a randomly chosen tree is greater than 140 inches?

Solution :

Mean - \mu = 112 inches

Standard deviation - \sigma = 14 inches

The z-score formula is given by, Z=\frac{x-\mu}{\sigma}

Now,

P(X>140)=P(\frac{x-\mu}{\sigma}>\frac{140-\mu}{\sigma})

P(X>140)=P(Z>\frac{140-112}{14})

P(X>140)=P(Z>\frac{28}{14})

P(X>140)=P(Z>2)

P(X>140)=1-P(Z

The Z-score value we get is from the Z-table,

P(X>140)=1-0.9772

P(X>140)=0.0228

Therefore, the probability that a randomly chosen tree is greater than 140 inches is 0.0228.
