Step-by-step explanation:
y > -15
y is bigger than -15
= -14 , -13 , -12 , -11 , -10 , etc . . .
Answer:
First one is 25/2
Step-by-step explanation:
12×2+1=25/2
9×4+1=36/4
cross multiply and you get
100/
divide both by 2 and you get 50/4 then you divide both by 2 again and you get 25/2 because you can't reduce it anymore
Exponents are numbers that are compressed. These numbers are simplified by finding a number that when multiplied by itself multiple times will get to the original number.
This sequence can be rewritten as:
10⁻¹; 10¹; 10²; 10³; 10⁴
Answer:
10 muffins
Step-by-step explanation:
10 is 25% (one-fourth) of 40
Answer:
68.268%
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = $1900
σ is the population standard deviation = $200
For x = $1700
z = $1700 - $1900/$200
z = -1
Probability value from Z-Table:
P(x= 1700) = 0.15866
For x = $2100
z = $2100 - $1900/$200
= 1
Probability value from Z-Table:
P(x = 2100) = 0.84134
The probabilty of the population that has a rent price between $1700 and $2100
P(x = 2100) - P(x = 1700)
0.84134 - 0.15866
= 0.68268
Converting to percentage
= 0.68268 × 100%
= 68.268%
The percentage of the population that has a rent price between $1700 and $2100 is 68.268%
