Answer:  C. 25

Step-by-step explanation:

Since, Here given expression,

2√ x + 20 = 15 + 3√ x  

⇒2√ x + 20 - 15 =  3√ x   (By subtracting 15 on both sides)

⇒2√ x + 5 =  3√ x  

⇒ 5 =  3√ x - 2√ x   (By subtracting 2 √ x on both sides)

⇒5 = ( 3-2)√ x

⇒√ x  = 5

⇒x = 25 (By squaring both sides )

Therefore, Option C is correct.

How long would take you to drive around the earth at 80mph
Bess [88]

Answer:

311.25 hours ; almost 13 days

Step-by-step explanation:

actually you will not able to drive a car all the way around the earth (the Pacific and Atlantic oceans are really big).

but According to the calculation it would take you around 311.25 hours ( almost 13 days) to drive the 24,900 miles around the circumference of the earth at its widest point (the equator).

because we know ,

t=s/v

 =(24,900/80)hours                    [ s= the circumference of the earth]

 =311.25 hours                              [v=Velocity]

An investigator examined cases of fetal death in 27,000 pregnancies and classified mothers according to whether they had experie
MariettaO [177]

Answer:

Correlation does not imply causation

Step-by-step explanation:

Correlation is a statistical technique which shows how strongly a pair of variables are linearly related and change together.

Causation says that the change in one value will cause the other to change, making one variable dependent on the other.

Examples of correlation with causation are:

a) ice cream sales and summer temperatures

b) forest fires and summer temperatures

An example of correlation without causation is ice cream sales and forest fires. While they both increase as temperatures increase, ice cream sales are not CAUSING the forest fires.

From the information available it can be suggested that there is a correlation between sexual intercourse within a month prior to delivery as there is a higher number of fetus deaths to mothers who had sexual intercourse within a month prior to delivery. However, there is no information which shows the sexual intercourse caused the deaths. Additionally, 89% of the mothers of fetuses who died DID NOT have sexual intercourse within a month prior to delivery, thus even the correlation is weak in this case.
