The answer to your problem would be A.
Answer:
3^2 = 9
9 x 3.14 = 28.26
28.26 divided by 4 = 7.065 (round) = 7.07
A^2+b^2=c^2
8^2+6^2=c^2
64+36=c^2
100=c^2
10=c
Final answer: 10 inches
Answer: 7/8
Step-by-step explanation: This is a substitution problem, from the expression x + ³/₄, where x = ¹/₈, we now replace or substitute for x and then solve the expression fractionally, the expression now becomes
¹/₈ + ³/₄
Now , find the l. c. m. of the denominator 8 and 4
1 + 6
= _____
8
= 7/8
NOTE: To get 1 and 6, you find out how many times 8 can go in the l. c. m. and later multiplied the number of times by the numerator which = 1.
And the number of times 4 can go in the l. c. m. (8) which is 2 times then multiplied by the numerator (3) = 6.
Adding 1 and 6 together gives 7/8.
Answer:
Explanation has been given below
Step-by-step explanation:
hope fully it may concern with 70% adults then
p = 0.77
randomly select = 6
then mean will be
mean = n * p = 6*0.77=4.62
To get variance np (1-p)
then putting values we get
np (1-p) = 4.62 *0.23 = 1.0626
taking square root we get
sd = 1.03
Most samples of 6 adults would differ from the mean by no more than 1 sd
mean is differ by no more than 2 sds .
In a real-life situation, it is expected that 4 or 5 of 6 to think it is a problem.
I would not expect 0, 1, or 2.
