Answer:
38 Students love math the most
Step-by-step explanation:
<u>Step 1: Find how much math is left</u>
Total: 90
Already said: 32 + 20 -> 52
Total - Already said = Math
90 - 52 = 38
Answer: 38 Students love math the most
Answer:
145
Step-by-step explanation:
A+B=180
so,180-35=145.
Answer:
x can be 4 so A
because the line under the greater sign it means it can be the same
Answer:
542
Step-by-step explanation:
We are required to find the sample size at 98% confidence interval in this question
E = 0.04
P* = 20% = 0.20
n = p* x (1-p)(Zα/2÷E)²
α = 1 - 0.98
= 0.02
To get Critical value
= 0.02/2 = 0.01
The critical value at 0.01 is 2.33
Inserting values into formula:
O.2 x 0.8(2.33/0.04)²
= 0.8 x 0.2 x 58.25²
= 542.89
The value of n must be an integer therefore the answer is 542.
Answer:
HELLO I am tried to solve your question and I found 2 answer
Step-by-step explanation:
firstly we need discriminant to find x values.
you know we use b²-4ac formule to find discriminant
and this value (-3)²-[4*√2*(-2√2)]=-7 this means X hasn't reel value. let's continue.. if we want to find x value we use disc. and [-b±√∆]/2a one x value is [3+√7i]/2√2. and other is [3-√7i]/2√2
