Three fifths of the children in a school are boys. 7/8 of the girls in the school are right-handed. What fraction of the childre
Kaylis [27]

Answer:

To find the answer we only need to know,

Total no.of girls and Total no.of right handed girls.

So,

Total no.of right handed girls = 7/8

Total no.of girls                        = 8/8 (as given in question)

Total no.of left handed girls is,

(Fraction of total no.of girls) - (Fraction of total no.of left handed girls)

= 8/8 - 7/8

= 1/8

∴ 1/8 of the girls in the school are left handed.

Probability of father and mother born in Michigan independent.<br><br>​
raketka [301]

Answer:

  A.  no, not independent

Step-by-step explanation:

Let A = "father born in Michigan" and B = "mother born in Michigan".

If A and B are independent, then ...

  P(A|B) = P(A)

The table tells us ...

  P(A|B) = P(A&B)/P(B) = 0.29/0.73 ≈ 0.397

and

  P(A) = 0.48

Since 0.48 ≠ 0.397, we must conclude that the events are not independent.

Use the formula for interest P=750 r=7% Y=25 A=?
Over [174]

Answer:

2062.50

Step-by-step explanation:

Interest = (Principle x rate x time)/100

Amount = Principle + interest

Principle = 750

Rate = 7%

Time = 25 years

(750 x 7 x 25)/100

= 131250/100

=1312.50

Principle = 750

Interest = 1312.50

Amount = 750 + 1312.50

Amount = 2062.50
