Answer:

Maria sent 7 messages

Bob sent 5 messages

Ahmad sent 45 messages

Step-by-step explanation:

Given that Maria, Ahmad, and Bob sent a total of 52 text messages during the weekend.

If Maria sent fewer messages than Bob, and Ahmad sent times as many messages as Bob

Since the exact figures were not given, then let make an assumption that Ahmad sent 9 times as many messages as Bob.

If Bob sent 5 messages, then, Ahmad will send 5 × 9 = 45 messages

Also, it is given that Maria sent fewer messages than Bob. Take 45 away from 52. That is,

52 - 45 = 7

Therefore,

Maria sent 7 messages

Bob sent 5 messages

Ahmad sent 45 messages

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
Natalija [7]

Answer:  C & D

<u>Step-by-step explanation:</u>

A binomial experiment must satisfy ALL four of the following:

  1.  A fixed number of trials
  2.  Each trial is independent of the others
  3.  There are only two outcomes (Success & Fail)
  4.  The probability of each outcome remains constant from trial to trial.

A) When the spinner is spun three times, X is the sum of the numbers the spinner lands on.

  → #3 is not satisfied  <em>(#4 is also not satisfied)</em>

B) When the spinner is spun multiple times ...

    → #1 is not satisfied

C)  When the spinner is spun four times, X is the number of times the spinner does not land on an odd number.

    → Satisfies ALL FOUR

  1.  A fixed number of trials = 4
  2.  Each trial is independent of the others = each spin is separate
  3.  There are only two outcomes = Not Odd & Odd
  4.  The probability of each outcome remains constant from trial to trial = P(X = not odd) = 0.50 for each spin

D) When the spinner is spun five times, X is the number of times the spinner lands on 1.

   → Satisfies ALL FOUR

  1.  A fixed number of trials = 5
  2.  Each trial is independent of the others = each spin is separate
  3.  There are only two outcomes = 1 & Not 1
  4.  The probability of each outcome remains constant from trial to trial = P(X = 1) = 0.17 for each spin

Mattie is making a collar for her dog. She needs to buy some chain,a clasp, and a name tag. She wants the chain to be 40 centime
Fantom [35]

Answer:the total cost of the collar is $5.11

Step-by-step explanation:

To make a collar for her dog, she needs to buy some chain,a clasp, and a name tag.

The length of the chain that she wants to buy is 40 centimeters.

1000 centimeters = 1 meter

40 centimeters = 40/1000 = 0.04 meters.

One meter of chain costs $9.75. Therefore, 0.04 meters of chain would cost

0.04 × 9.75 = $0.39

The clasp is $1.29 and the name tag is $3.43. Therefore, the total cost of the collar would be

0.39 + 1.29 + 3.43 = $5.11
