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)

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
