What is the product of 2.31 and 0.21?
Solution:
We need to find 2.31*0.21
Let us first find 231*21, then we would consider decimals
231*1=231
231*2=462
So, 231*21=231+4620=4851
So, we get 231*21=4851
But, we need to find, 2.31*0.21
There are two numbers after decimal in 2.31 (3 and 1). and, there are two numbers after decimal in 0.21(2 and 1)
So, In result of, 2.31*0.21 there must be four digits after decimal.
As, 231*21=4851
So, 2.31*0.21=0.4851 (four digits after decimal)
Answer:0.4851
Answer:
Answer H.
Step-by-step explanation:
No they don't lie on the same line because all coordinate points would be at different distances from the origin. The only way a point could be at the same line as the others would be they would have to have the same x- or y- axis points. (For example: 6,5; 3,5; and 2,5 would all be on the same line, horizontally, because the 5 in all three coordinates refers to the y- axis aka the horizontal axis
Answer:
a) 1504
b)
Step-by-step explanation:
A
a. no of people that are male = 42
b. no of people that study biology = 34
c. no of people that do both = 1428(42 × 34)
d. no of people that are Male or study biology or both = 42 + 34 + 1428= 1504
B.
a.no of people that are male or female = 90
prob(male) = 14 ÷ 90
= 0.16
b. prob(bio) = 34 ÷ 34
= 1
c.prob(both) = 0.16
d. prob(all) = 0.16 + 1 + 0.16
= 1.32
