Answer:
The height of the sunflower plant is 1.57 meters.
Step-by-step explanation:
Initially, the height of the sunflower plant was of 1.25 m.
Then, it grew by 0.32 m, that is, we have to add 0.32 m to the height.
Sum of decimals:
Dot below dot, add normally. So
1.25
+0.32
---------
1.57
So
The height of the sunflower plant is 1.57 meters.
Answer:
3972.72 specimens
Step-by-step explanation:
We solve using the z score formula:
z = (x-μ)/σ where
x is the raw score = 73 cm
μ is the population mean = 147 cm
σ is the population standard deviation = 30 cm
N is the number of samples = 4000
For x > 73
z = 73 - 147/30
z = -2.46667
Probability value from Z-Table:
P(x<73) = 0.0068189
P(x>73) = 1 - P(x<73) = 0.99318
The probability of having a height greater than 73cm is: 0.99318
The number of specimens that have a height greater than 73cm is calculated as: 0.99318 × 4000
= 3972.72 specimens

Add 3 to 72... so 3 plus 72 is 75
X=75
Step-by-step explanation:
it is a line, so that is 1 point, where it cuts the x-axis.
in general that means y = 0.
so,
0 = 4x - 3
4x = 3
x = 3/4
the point, where the line cuts the x-axis is
(3/4, 0)
