Answer:
Step-by-step explanation:
2.25m + 2(2.25m) + 90 cm =
2.25m + 4.50m + 90 cm
6.75m + 90 cm
1 cm = 0.01m...so 90 cm = 90 * 0.01 = 0.9m
6.75m + 0.9m = 7.65m <===
Answer:
2.5 cm
Step-by-step explanation:
We see the diameter is 5cm
so the radius is half the diameter
5/2 = 2.5 cm
Answer:
three consecutive odd integers are.

Step-by-step explanation:
Let x be the first term of odd integer,
Therefore, the second consecutive odd integers = 
Similarly, the third consecutive odd integers = 
Given:
The sum of the first term and second term is 344.
first term + second term = 344
Here first term is x and second term is
.





Therefore, the first odd integers is 171.
And the second consecutive odd integers = 
Similarly, the third consecutive odd integers = 
The value of z-score for a score that is three standard deviations above the mean is 3.
In this question,
A z-score measures exactly how many standard deviations a data point is above or below the mean. It allows us to calculate the probability of a score occurring within our normal distribution and enables us to compare two scores that are from different normal distributions.
Let x be the score
let μ be the mean and
let σ be the standard deviations
Now, x = μ + 3σ
The formula of z-score is

⇒ 
⇒ 
⇒ 
Hence we can conclude that the value of z-score for a score that is three standard deviations above the mean is 3.

Answer:
26.4% decrease
Step-by-step explanation:
The amount of change is ...
2500 -1840 = -660
As a percentage of the original price, that is ...
-660/2500 × 100% = -26.4% . . . . . negative change = decrease
The decrease is 26.4%.
