Answer:
Think about the additive inverse property. any number plus it's inverse =0. the inverse of -5 = 5. adding -5+5 = 0.
5 is your answer.
Answer:
81.9%
Step-by-step explanation:
In a data set with a normal distribution the mean is 59 and standard deviation is three about what percent of the data live between 53 and 62
Using z score formula
z = (x-μ)/σ, where
x is the raw score,
μ is the population mean = 59
and σ is the population standard deviation = 3
For x = 53
z = 53 - 59/3
= -2
P-value from Z-Table:
P(x = 53) = 0.02275
For x = 62
z = 62 - 59/3
= 1
P-value from Z-Table:
P(x = 62) = 0.84134
Hence, the probability of the data live between 53 and 62 is
0.84134 - 0.02275
0.81859
Converting to Percentage.= 0.81859
× 100 = 81.859%
Approximately = 81.9%
Answer:
8x+12y<=192
Step-by-step explanation:
Create an inequality to represent Cheryl's situation, where x is the number of 8-ounce jars, and y is the number of 12-ounce jars.
8x+12y<=192
To graph the inequality, rewrite it in slope-intercept form.
8x+12y<=192
12y<=-8x+192
y<=-(2)/(3)x+16
Graph the boundary line as solid, with a y-intercept at (0,16) and a slope -2/3 of. Then, shade the half-plane below the line.
The answer is C because there are 4 minutes in between 18 and 21, so you add 24+4 since she made 24 bracelets. (Hint: she has already made 24 bracelets in 18 minutes, the number should not go down so it would not be A, B, or D)
