The team scored twenty-three points in total.
This word sum can be worked out as follows:
Three field goals worth three points each is equal to nine points (3 x 3 = 9).
Two touchdowns were scored; each touchdown is worth six points. This equals twelve points (2 x 6 = 12).
Lastly, the team was awarded a bonus point for each touchdown they scored. They scored two touchdowns so they were awarded two extra points (2 x 1 = 2).
Therefore, we have three subtotals: nine for the field goals; twelve for the touchdowns and two for the bonus points. The equation for this word sum is 9 + 12 + 2 = 23
Answer:
360
Step-by-step explanation:
The formula for the sum of an infinite geometric series is a₁/(1-r), where a₁ represents the first value and r represents the ratio. We can plug in our values here to get
a₁/(1-r) = 240/(1-1/3)
= 240 / (2/3)
= (240/1) / (2/3)
= (240/1) * (3/2)
= 360
Answer:
294.1 pounds
Step-by-step explanation:
Step 1
We find the z score for 90th percentile
= 1.282
Step 2
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score ??
μ is the population mean = 230 pounds
σ is the population standard deviation= 50 pounds
1.282 = x - 230/50
Cross Multiply
1.282 × 50 = x - 230
64.1 = x - 230
x = 230 + 64.1
x = 294.1 pounds
The birth weight of elephants at the 90th percentile is 294.1 pounds.
that simply means, is a vertical line, check the picture below.
