Answer:
3.36 cm
Step-by-step explanation:
from the passage before ; the figure of question is similar to the first figure in passage because those triangles have an each equal angle.
Therefore the ratio of side is equal ; 1/0.84=4/x
Solve equation will be x(1)=4(0.84) ; x=3.36 cm
Answer:
Step-by-step explanation:
The normal distribution curve standard is bell shaped having mean =0 and std devition =1.
This is symmetrical about the y axis i.e. mean. More than 99% of the area under the curve lie between z=-3 to z=3
To find the area to the right of z =0.05 is equivalent to
calculating the
Probability that Z >0.05
= P(Z>0.05)
=0.5-0.0199
=0.4801

I don't no be cause i don't really do this kind of stuff
Answer:
a) 5, 6
b) 8, 9
c) 9, 10
Step-by-step explanation:
It is useful to know the squares of small integers:
5² = 25
6² = 36
7² = 49
8² = 64
9² = 81
10² = 100
Then the problem becomes one of identifying the perfect squares the given number lies between
a) 25 < 35 < 36 ⇒ 5 < √35 < 6
b) 64 < 67 < 81 ⇒ 8 < √67 < 9
c) 81 < 93 < 100 ⇒ 9 < √93 < 10
Answer:
The greatest common factor of this would be 3x^2y
Step-by-step explanation:
In order to find this, first find the greatest common factor of the coefficients. Since 3 goes in evenly to both 15 and -18, then we know that it is a common factor.
From there we need to find the number of x's. Since the first term only has 2 x's and the second has 3, we take the lowest number. (x^2)
And since the first term has 3 y's and the second has just 1, we take the lowest number (y).
