german

Maximum number of mangoes that Camila can buy are 5

Step-by-step explanation:

Step 1: Find the cost of 8 apples bought by Camila.

Cost of 1 apple = $0.50

Cost of 8 apples = $0.50 × 8 = $4

Step 2: Find the remaining amount with Camila after she bought 8 apples.

Total amount that can be spent = $7.75

Cost of apples = $4

Remaining amount = $7.75 - $4 = $3.75

Step 3: Find the number of mangoes she can buy

Cost of 1 mango = $0.75

Number of mangoes = $3.75/$0.75 = 5

There are 15 technicians and 11 chemists working in a research lab. They need to form a 5 person safety committee. In how many w

Burka [1]

<h2>There are a total 65,780 ways in which the committee can be made of 5 members.</h2>

Step-by-step explanation:

Here, the total number of technicians in the lab = 15

The total number of chemists in the lab = 11

So, the total members in the lab = 15 + 11 = 26

So, there are total 26 eligible candidates in the lab from which committee of 5 people has to be made.

Now, since there is <u>no restrictions</u> on the choice, so the committee can be formed in nay way, such that:

It may or may not have any technician.

It may or may not have may chemists.

So, the number of ways 5 member can randomly be chosen from a committee of 26 people = $^{26} C_5$

$^{26} C_5$ = $^{26} C_5 = \frac{26!}{5! \times 21!} = 65,780$

Hence, there are a total 65,780 ways in which the committee can be made of 5 members.

Write a system of equations to describe the situation below, solve using substitution, and fill

Lynna [10]

Answer:

The cost must be $32 since that is the only cost possible for the 1st deal

Step-by-step explanation:

Let C represent the total cost of each deal

Let T be the number of trips down the water slide

C = 32 for the 1st deal since the cost is the same regardless of how much she rides

C = 18 + T for the 2nd deal

To find when the two costs are equal set them equal to each other and solve for T

32 = 18 + T

T = 14 trips

The cost must be $32 since that is the only cost possible for the 1st deal

The probability of drawing two red cards without replacement is 25/102 , and the probability of drawing one red card is 1/2 .

sergey [27]

Answer:

The probability of drawing a second red card, since the first card is red is 25/51

Step-by-step explanation:

The probability of drawing a second red card since the first Card is red is:

P (R2 | R1) = P (R2 and R1) / R1

So:

P (R2 | R1) = (25/102) / 1/2

P (R2 | R1) = 25/51

Therefore the correct option is option 2.

the probability of drawing a second red card, since the first card is red is 25/51
