andrew11 [14]

Answer:

2b < 56

n = b - 2

b = n + 2

n < 27

b < 28

No, because the difference between Brittany and Nate's age is 2years

Step-by-step explanation:

A.)

Twice Brittany’s age is less than the age of Abraham Lincoln when he died. President Lincoln was 56 years old at the time of his death

Let Brittany's age = b

Twice Brittany's age = 2 × b = 2b

Lincoln's age = 56

2b < 56

B.)

Nate's age = n

Nate is 2 years younger than brittany who is aged 'b'

n = b - 2

C.) b = n + 2

D.)

If 2b < 56 and b = n + 2

2(n + 2) < 56

2n + 2 < 56

2n < 56 - 2

2n < 54 ; n < 27

2b < 56

b < 56/2

b < 28

No, because the difference between Brittany and Nate's age is 2years

Find the probability of 3 successes in 7 trials of a binomial experiment in which the probability of success in any one trial is
natita [175]

Answer: 0.07

Step-by-step explanation: Since it is a binomial experiment , we will use the formula:

n C r p^{r}q^{n-r}

p = 0.35

q = 1 - 0.35 = 0.65

n is the number of trials = 7

r = 3

substituting into the formula, we have

7 C 3 (0.35^{3}0.65^{7}

= 35(0.35^{3}0.65^{7}

=0.0736

to the nearest tenth

= 0.07
