The answer is 20! hope this helps
A perfect square is what u get when u multiply 2 of the same numbers together.
For example : 2 * 2 = 4.....4 is a perfect square
3 * 3 = 9...9 is a perfect square
4 * 4 = 16....16 is a perfect square
2 cannot be a perfect square because u cant multiply anything by itself that equals 2.
so ur perfect square numbers are : 1,4,9,25,36,81,144,225,400
The alternative and null hypotheses is given below,
Null Hypothesis, H0: μ1 - μ2 = 0
Alternative Hypothesis, Ha: μ1 - μ2 < 0
Compound Variance is given as,
sp = sqrt( s12n1+s22n2)
sp = sqrt(16973 + 112.3673)
sp = 1.9632
Test statistic of z is,
z = (x1bar - x2bar)/sp
z = (69 - 71)/1.9632
z = -1.02
P-value Approach, P=0.1539 as long as P>= 0.
As P-value >= 0.01, failing to rule out the null hypothesis.

What is known as a decimal mark?</h3>
To differentiate between a whole number and its fractional component, a decimal point is used either as a point or a dot. It is also referred to as a decimal mark. The symbol for the decimal point is (.). In daily life, decimals are also frequently used. That whenever a shirt costs $10.50, for instance, the price can be written as 10.50.

<span>Solve
3x+y= -6
y=2/3x + 5
</span>Answer:
<span>x=<span>−3</span></span>
Answer:
3 or D
Step-by-step explaintain
Your problem statement tells you
f(x) passes through point (3, negative 1)
g(x) passes through point (3, negative 1)
This tells you the input value that produces the same output value for the two functions is 3, and that output value is -1.
