We need to see how many news papers she can deliver in one hour.

4 hours : 448 newspapers

1 hour : x newspapers

We need to divide 448 by 4 to keep both sides equal.

448÷4=112

So, Jayda delivers 112 newspapers per hour.

Answer:

Number 1 can form a right triangle. Numbers 2 & 3 cannot.

Step-by-step explanation:

To check if the sides are a right triangle, check if the sum of the squares of the two smaller sides equals the length of the square of the longest side. In other words, do the Pythagorean Theorem.

5² + 12² = 13²

25 + 144 = 169

169 = 169

<u><em>They are equal therefore Number 1 can form a right triangle.</em></u>

5² + 7² = 9²

25 + 49 = 81

74 = 81

<em>They are not equal, therefore Number 2 can't form a right triangle.</em>

<em />

10² + 12² = 30²

100 + 144 = 900

244 = 900

<em>They are not equal, therefore Number 3 can't form a right triangle.</em>

In a certain country, the true probability of a baby being a girl is 0.469. Among the next seven randomly selected births in th

-BARSIC- [3]

Answer:

The probability is 0.995 ( approx ).

Step-by-step explanation:

Let X represents the event of baby girl,

The probability of a baby being a girl is, p = 0.469,

So, the probability of a baby who is not a girl is, q = 1 - 0.469 = 0.531,

Also, the total number of experiment, n = 7

Thus, by the binomial distribution formula,

$P(x)=^nC_x(p)^x q^{n-x}$

Where, $^nC_x=\frac{n!}{x!(n-x)!}$

The probability that all babies are girl or there is no baby boy,

$P(X=7)=^7C_7(0.469)^7(0.531)^{7-7}$

$=0.00499125661758$

Hence, the probability that at least one of them is a boy = 1 - P(X=7)

= 1 - 0.00499125661758

= 0.995008743382

≈ 0.995
