Answer: 
Step-by-step explanation:
given data:
height of the statue = 80m.
base of the statue = 
.
scale of the statue replica = 1:15.
<u><em>solution:</em></u>
=
the area of the replica is
Answer:
The length would be 5 meters
Step-by-step explanation:
To get this value, start with the area formula.
A = LW
Next input the known values for area and width
1 = L1/5
Now multiply each side by 5
5 = L
Answer:
H0 : μ1 - μ2 = 0
H1: : μ1 - μ2 ≠ 0
we reject the Null and we conclude that babies prefer actual speaking to humming.
Step-by-step explanation:
H0 : μ1 - μ2 = 0
H1: : μ1 - μ2 ≠ 0
Mean difference, d = 27.79
Standard deviation of difference, Sd = 63.18
Sample size, n = 50
The test statistic :
d / (Sd / √n)
Test statistic :
27.79 / (63.18 / √50)
27.79 / 8.9350012
= 3.11
Using the Test statistic score, we can obtain the Pvalue
Using the standard normal table ;
Pvalue = P(x<-Z or x>Z) = 0.0018709
Pvalue is very low
Pvalue < α ; Hence, we reject the Null and we conclude that babies prefer actual speaking to humming.
Step-by-step explanation:
Simplify the following:
(((-3)/4)^5)^2
Multiply exponents. (((-3)/4)^5)^2 = ((-3)/4)^(5×2):
((-3)/4)^(5×2)
5×2 = 10:
((-3)/4)^10
((-3)/4)^10 = (-3)^10/4^10:
(-3)^10/4^10
(-3)^10 = (-1)^10×3^10 = 1×3^10:
3^10/4^10
4^10 = (4^5)^2 = (4×4^4)^2 = (4 (4^2)^2)^2:
3^10/(4 (4^2)^2)^2
4^2 = 16:
3^10/(4×16^2)^2
3^10/(4×256)^2
4×256 = 1024:
3^10/1024^2
3^10/1048576
Answer=3^10 / 2^20
