Answer:
t = -0.061
Step-by-step explanation:
We are given;
Population mean; μ = 5.9
Sample mean; x¯ = 5.6
Sample size; n = 24
standard deviation; σ = 1
Significance level = 0.02
Formula for the test statistic since sample size is less than 30 is;
t = (x¯ - μ)/(σ/√n)
t = (5.6 - 5.9)/(1/√24)
t = -0.3/(1/√24)
t = -0.061
<span>4(x2 – 2) = 28
4x^2-8=28 Distributive law of multiplication
4x^2+8=28+8 Additive identity
4x^2=36 ; adding 8 to both sides
x^2 =9, dividing both sides by 4
x= +/- 3</span>
Answer:
50 is greater.
Step-by-step explanation:
50 is greater because the value 5 in 50 has more value than the 4 in 43.
Answer:
so 24 is the answer
Step-by-step explanation:
first 1/4 is 20 out of 60
Second, we have to work out one fifth. The easiest way to do this is to divide 60 by five.
60 divided by 5 = 12
(We should know this from our times tables, 5x12=60)
We then times the fifth by three to work out three fifths.
12 x 3 = 36
We can then check this by working out two fifths and checking that both the answers add up to make 60.
We work out two fifths the same way we work out three, timesing by the value for one fifth.
12 x 2 = 24
24 + 36 = 60
So we know that we were correct and our final answer is
3/5 of 60 = 36.
then 24 + 36 = 60
so 24 is the answer
Answer:
25inch
Step-by-step explanation:
Ok so there is something called a Pythagorean theorem.
It's a²+b²=c²
It works on right triangles
C is the longest side or the side not touching the right angle
and a and b is the other 2 sides
so the missing side is 24²+7²=Missing side or c²
24²=576 and 7²= 49
576+49=625
=25
