Answer:

1) 18 yards

2) x = 24

3) 36 yards

4) y = (-9/98)(x - 24)² + 18

Step-by-step explanation:

The path is symmetrical about x = h

h = (10+38)/2 = 24

x = 24

Distance = 18 + 18 = 36

Vertex: (24,18)

y = a(x - 24)² + 18

At t = 10, y = 0

0 = a(10 - 24)² + 18

a = -18/14²

a = -18/196 = -9/98

y = (-9/98)(x - 24)² + 18

A beekeeper pours honey into jars. Each large jar holds 18 ounces of honey. Each small jar holds 12 ounces of honey. The beekeep

ArbitrLikvidat [17]

Answer: 1100 ounces because 20 × 30 + 10 × 50 = 1100

Step-by-step explanation:

Amount of honey contained in each large jar = 18 ounces

Number of large jar filled = 32

Total amount of honey in large jars:

= 18 ounces × 32

= 576 ounces

Amount of honey contained in each small jar = 12 ounces

Number of small jars filled = 46

Total amount of honey in small jars:

= 12 ounces × 46

= 552 ounces

The total amount of hones in the jars will be the addition of the honey in the small and large jars. This will be:

= 576 ounces + 552 ounces

= 1128 ounces

The most reasonable estimate will be:

1100 ounces because 20 × 30 + 10 × 50 = 1100

In a horse race with 5 horses, you make a bet by predicting the ranking of all 5 horses. Suppose you place your bet at random. W

lapo4ka [179]

Answer:

P( top two horses are predicted incorrectly in incorrect order)

= $\frac{1}{2}$

Step-by-step explanation:

In the horse race the outcome can be predicted in 5! = 120 ways.

Now suppose the top two horses were predicted incorrectly in incorrect order. Now, the top horse can be predicted incorrectly in 4 ways.

Suppose the top horse was predicted to be in k-th position where k = 2, 3 ,4,5

so the second horse can be predicted to be in place from 1 to (k - 1)

So, the top two horses can be predicted incorrectly in incorrect order

in $\sum_{k =2}^{5}(k - 1)$ = 10 ways

and for each prediction of the two the remaining horses may be predicted in 3! = 6 ways.

Hence ,

P( top two horses are predicted incorrectly in incorrect order)

= $\frac{6 \times 10}{120}$

= $\frac{1}{2}$
