In a math class of 35 students, 17 boys and 18 are girls. On a unit test, 8 boys and 12 girls made an A grade. A student is chosen at random from the class. What is the probability of choosing a boy or an A student? Group of answer choices

0.57

0.71

0.83

0.09

.83

Step-by-step explanation:

In order to find the probability that either a boy or an A student is chosen, you must first identify how many boys and A students there are altogether in the class:

9 boys who are not A students + 8 boys who are A students + 12 girls who are A students = 29 students are either boys or A students

Now, you just need to turn this into a probability:

1: 29/35 (given)

2: ≈82.86/100 (multiply both the numerator and denominator by 100/35)

3: ≈83% or .83 (round to the ones place and turn into a decimal)

step-by-step explanation:

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week
