Answer:

The total number of flowers is 680

Step-by-step explanation:

Let

x -----> the number of flowers green

y ----> the number of flowers yellow

z ----> the number of flowers purple

we know that

x=\frac{3}{10}(x+y+z) ----> equation A

The rest is equal to

\frac{7}{10}(x+y+z)

so

y=(\frac{3}{4})\frac{7}{10}(x+y+z)

y=\frac{21}{40}(x+y+z) -----> equation B

z=(\frac{1}{4})\frac{7}{10}(x+y+z)

z=\frac{7}{40}(x+y+z) -----> equation C

Remember that

z=119

substitute in equation C and solve for (x+y+z)

(x+y+z) ----> is the total of flowers

119=\frac{7}{40}(x+y+z)

(x+y+z)=119(40)/7

(x+y+z)=680

<em>Find the value of x</em>

substitute in the equation A

x=\frac{3}{10}(680)=204

<em>Find the value of y</em>

substitute in the equation B

y=\frac{21}{40}(680)=357

therefore

The number of flowers green is 204

The number of flowers yellow is 357

The he number of flowers purple is 119

The total number of flowers is 680

The data represent the results for a test for a certain disease. Assume one individual from the group is randomly selected. Find
SOVA2 [1]

Answer:

0.505 = 50.7% probability of a negative test.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

142 + 6 = 148 people tested positive. Of those, 142 had the disease and 6 did not.

7 + 145 = 152 people tested negative. Of those, 7 had the disease and 145 did not.

Find the probability of getting someone who tests negative, given that he or she did not have the disease.

This is the probability of a negative test.

152 negative tests out of 148 + 152 = 300

152/300 = 0.507

0.505 = 50.7% probability of a negative test.

Many games depend on how a ball bounces. For example, if different basketballs rebounded differently, one basketball would bounc
Crank

Answer:

Basketball = 0.743

Step-by-step explanation:

Given

Tennis:

Starting Height = 200 cm

Rebound Height = 111 cm

Soccer Balls;

Starting Height = 200 cm

Rebound Height = 120 cm

Basketball:

Starting Height = 72 inches

Rebound Height = 53.5 inches

Squash:

Starting Height = 100 inches

Rebound Height = 29.5 inches

For measuring the bounciness of a ball, one needs that starting Height of and the rebound Height of that ball which have been listed out above.

Calculating the rebound ratio of each balls.

Rebound Ratio = Rebound Height/Starting Height

Tennis: 111/200= 0.556

Soccer Balls: 120/200 = 1.667

Basketball: 53.5/72 = 0.743

Squash: 29.5/100 = 0.295

From the rebounding ratio calculated above, it can be seen that basketball has the highest rebound ratio of 0.743 and is the bounciest of all whole Squash has the least rebound of 0.295 ratio, hence it is the least bounce of all.
