Bailey and Elena compete in a swim race.Their times are shown

Setler [38]

Answer: Bailey won the race by about 4 seconds.

Step-by-step explanation:

The whole second is the first number to the left of the decimal (_.)

So, 35.78 = 36 because 7>5.

39.51 = 40 because 5 = 5.

40 - 36 = 4.

About 7% of men in the United States have some form of red-green color blindness. Suppose we

Afina-wow [57]

Answer:

<h2>The probability will be $\frac{9538}{37345}$ </h2>

Step-by-step explanation:

<u>Let the total population of United States is 100.</u>

As per the given scenario, among them 7 men have the red-green color blindness.

Among the 4 selected males having at least 1 man having color blindness there could be total 4 possible cases.

CASE 1:

1 of the 4 men having blindness.

The probability will be $\frac{7C1\times93C3}{100C4} = \frac{7\times\frac{93\times92\times91}{6} }{\frac{100\times99\times98\times97}{24} } = \frac{28\times93\times92\times91}{100\times99\times98\times97}$

CASE 2:

2 of the 4 men having blindness.

The probability in this case will be $\frac{7C2\times93C2}{100C4} = \frac{7\times6\times\frac{93\times92}{2} }{\frac{100\times99\times98\times97}{24} } = \frac{56\times93\times92}{100\times99\times98\times97}$

CASE 3:

3 of the 4 men having blindness.

The required probability is $\frac{7C3\times93C1}{100C4} = \frac{7\times6\times\frac{93\times5}{6} }{\frac{100\times99\times98\times97}{24} } = \frac{35\times93\times24}{100\times99\times98\times97}$

CASE 4:

All of the 4 men that will be chosen, have the blindness.

In this case all of the men will be chosen from the 7% of the total population.

Hence, the probability is $\frac{7C4}{100C4} = \frac{7\times6\times5\times4 }{100\times99\times98\times97 } = \frac{35\times24}{100\times99\times98\times97}$

As any of the above 4 cases could be possible, in order to get the desired answer we need to add them.

hence, the answer is $\frac{9538}{37345}$

Trevor is swimming laps to raise money for the local food bank. He earns $1.85 per lap and has already swum 23 laps.

Studentka2010 [4]

Answer: L greater than 31

Step-by-step explanation:

Trevor is swimming laps to raise at over 100 dollars for the local food bank. He earns $1.85 per lap and has already swum 23 laps.

This means that the total amount that he has raised is number of laps that he has swum × the amount he earns per lap. Therefore,

Amount that he has already raised

= 1.85 × 23 = $42.55

100 - 42.55 = 57.45

He still needs to raise an amount greater than $57.45

To raise this amount, he needs to swim more laps. Number of laps that he needs to swim will be

57.45/1.85 = 31.05

Approximately 31 laps

Let the number of laps that he needs to swim be L

The inequality to show how many more laps Trevor needs to swim in order to raise more than $100 will be

L greater than 31

Emilys family loves to work together in the garden. They have a slight preference for flowers, as 60% their plants are flowers a

Alex73 [517]

Answer:

Number of Flowering Plants = 30

Number of vegetable plants = 20

Step-by-step explanation:

Im assuming the question is asking for the number of vegetables and number of flowers.

We need to convert 60% and 40% to decimal. The process is dividing by 100. Hence,

60% = 60/100 = 0.6

and

40% = 40/100 = 0.4

We multiply these with the total number to get number of vegetable and flowering plants.

So,

Number of Flowering Plants = 0.6 * 50 = 30

Number of vegetable plants = 0.4 * 50 = 20
