Answer:
0.07072
Step-by-step explanation:
Red Blocks= 31
Green Blocks= 47
Yellow blocks = 23
Purple blocks= 24
Total= 31+47+23+24= 125
P(Yellow) = 23/125
P(Purple)=24/125
NOTE: AND (X), OR (+)
P(yellow yellow or purple purple)
= P(Y and Y) + P(P and P)
=(23/125 X 23/125) + (24/125 X 24/125)
=529/15625 + 576/15625
=1105/15625
=221/3125
=0.07072
Therefore:
Probability of Picking Yellow Yellow or Purple Purple is 0.07072.

thousandths - 23 thousandths=how many hundredths and thousandths?
Let us first solve this and get the difference of the given numbers.
=> 56 thousandths = 0.056 (there are 5 hundredths and 6 thousandths)
=> 23 thousandths = 0.023 (there are 2 hundredths and 3 thousandths)
=> 0.056 – 0.023 = 0.033 is the answer
there 3 hundredths and 3 thousandths value left after subtracting the given 2
decimal numbers.</span>
Answer:
25.4, 28.6
Step-by-step explanation:
Given parameters
sample size, n = 24
sample mean, X = 27
population standard deviation, s = 3
critical value, Zα/2, where α = 0.01
99% confidence Interval, CI, is given as follows
CI = X ± Zα/2 × (s/√n)
Zα/2 = Z0.01/2 = Z0.005 = 2.576
CI = 27 ± 2.576 × (3/√24)
= (25.42 ,28.57)
Answer:
70
81
95
A: 46%
Step-by-step explanation:
29+41=70
135-54=81
205-110=95
A: 95 out of 205.
Divide 95 by 205.
or 0.46341...
Switch to % and Round.
46%
I actually have no idea what b and c mean so good luck
