c) Pick the correct symbol: p Correct = 0.65
d) What is the probability that exactly 79 of them grow into a healthy plant? Round final answer to 4 decimal places.
e) What is the probability that less than 79 of them grow into a healthy plant? Round final answer to 4 decimal places.
f) What is the probability that more than 79 of them grow into a healthy plant? Round final answer to 4 decimal places.
g) What is the probability that exactly 80 of them grow into a healthy plant? Round final answer to 4 decimal places.
h) What is the probability that at least 80 of them grow into a healthy plant? Round final answer to 4 decimal places.
i) What is the probability that at most 80 of them grow into a healthy plant Round final answer to 4 decimal places.
X=7
Explanation:
A triangle equals 180°, and they gave us one length already, and it says the one arm of the triangle is equal to the other so we know that the third angle is going to be the same as the second angle.
180=90+(6x+3)+(6x+3)
Combine like terms
180=96+12x
Subtract 96 from both sides
84=12x
Divide 12 by both sides
7=x
Now check it,
90+(6*7+3)+(6*7+3)
90+(45)+(45) =180
Answer:
150 cm.
Step-by-step explanation:
There 6 squares in a cube.
**SQUARES HAVE EQUAL SIDES.**
To find the area of an individual square, multiply the side length by itself twice. (x^2)
The side lengths of the squares are 5.
5 x 5 = 25.
25 is the area of each individual square.
Since there are 6 squares in total, multiply 25 by 6.
25 x 6 = 150.
Therefore, 150 cm is the surface area of the cube.
