Answer:
the ration is 3:7r
Step-by-step explanation:
Answer:
The initial amount a = 1
The growth or decay factor = 0.01025
Step-by-step explanation:
The exponential function.
y = 0.01025^x
The initial amount a = 1
The growth or decay factor = 0.01025
The exponential equation can be rewritten as Y = 1(0.01025)^x
Answer:
150 and 240 are the two numbers having difference as 90 and ratio as 5 : 8.
Step-by-step explanation:
Since ratio of two numbers is 5 : 8 ,
lets assume two numbers be 5x and 8x.
Difference of two numbers = 8x - 5x = 90
⇒3x =90
⇒x = 90/3=30
so two numbers are 5x = 5 × 30 = 150 and 8x = 8 × 30 = 240
Hence 150 and 240 are the two numbers having difference as 90 and ratio as 5 : 8.

Answer:
D. -1.75°C
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Assume that the mean reading is 0degrees°C and the standard deviation of the readings is 1.00degrees°C. This means that .
Find the temperature reading that separates the bottom 4% from the others.
The bottom 4% if the 4th percentile.
This is the value of X when Z has a pvalue of 0.04. This is .
The correct answer is:
D. -1.75°C
