Answer:
4
Step-by-step explanation:
Add up all the frequencies given
5+6+5+6+5+8+4+4+3 = 46
The total frequencies with the missing data value should add up to 50
50 = 46 + x
x = 50 - 46
x = 4

Answer:
(-3,-43) and (3,107)
Step-by-step explanation:
input 25x+32 for y
25x+32=5x²+25x-13
32=5x²-13
-5x²=-45
x²=9
x=+-3
which means you separate the solution
x= -3
x= 3
then input the answers you got for x, in both equations. Then you'll get your y.
y=25(-3)+32
-43
Then check your answer.
Then input the other answer you got for x.
I may be wrong, but I tried and checked my answers.
-4x*3/15-2x*5/15=-12x/15-10x/15=(-12x-10x)/15=-22x/15
The probability that the fourth digit is 4 is 1/6.
<h3>What is the probability?</h3>
Probability is used to calculate the odds that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
Probability the number is 4 = 1 / possible numbers
Possible numbers = 4, 5, 6, 7, 8, 9,
= 1/6
