Answer:

5 out of 12

5/12

January, March, May, June, July

There are three months whose name starts with the letter 'j': January, June, July

There are two months whose name starts with the letter 'm': March, May

So altogether, there are 5 months whose name starts with the letter 'j' or 'm'. So the possible outcome is 5 and total number of sample space is 12.

Therefore the required probability is: 5/12

PLEASE GIVE BRAINLYEST :)

Answer:

Step-by-step explanation:

Total outcomes = 12

Letter starting with M = 2 (march & May)

Letter starting with J = 3 ( January, June, July)

P(letter starting with M and J)=2/12+3/12=5/12

1) How many 3/4 does it take to make 9/2?


     Now look at this, 3/4 x 6 = 4 1/2.  4 1/2 is the same as 9/2


   3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4 ---> takes 6, 3/4's to make 9/2

2)  How many 3/4's go into 9/2?


    This is the same question as the 1st one so the answer is 6 :)


3)  9/2 divided by 3/4 = ??


         Use the KEEP< CHANGE< FLIP method, so it turns into  I
                                                                                                    I
                                                                                                    I
                                                                                                    I
      9/2 x 4/3                       < -------------------------------------          I


  This is equal to 36/6 which is 6 :)


The answer is 6 for numbers 1, 2, and 3 :)

I have the formula <br><br> A fraction • π r^2
MatroZZZ [7]

Answer:

22.2 ft²

Step-by-step explanation:

The area (A) of a sector is calculated as

A = area of circle × fraction of circle

  = πr² × \frac{50}{360}

  = π × 7.13² × \frac{5}{36}

  = \frac{7.13^2(5)\pi }{36} ≈ 22.2 ft² ( nearest tenth )

50 students were asked what they did last night. 16 said they read a book, 41 said they watched TV, 7 said they did neither, how
Kamila [148]

Answer:

14 students

Step-by-step explanation:

Given

Let:

b \to read a book

t \to watched TV

So, we have:

n = 50 -- total

b = 16

t = 41

none = 7

Required

Students that did both (x)

This is calculated using:

Total = Books\ only + TV\ only + Both + None

So, we have:

n = (b - x) + (t - x) + x + none

This gives:

50 = (16 - x) + (41 - x) + x + 7

Open brackets

50 = 16 - x + 41 - x + x + 7

50 = 16 - x + 41 +7

Collect like terms

x = 16 - 50 + 41 +7

x = 14

<em>Hence, 14 students did both</em>

1. What number, when substituted for x in the following problem, will make the problem true?
riadik2000 [5.3K]

Answer:

x = 17.82

Step-by-step explanation:

6x + 8% = 107    

      -8%    -8%

or

107 - 0.08 = 106.92

-----------------------------------

6x = 106.92

÷6      ÷6

x = 17.82

------------------------------------

I hope this helps!
