900-573=327 To reach their goal the least amount of books they need to read is 327
Answer:
We have strong evidence that on average, students study less than 150 minutes per night during the school week
Step-by-step explanation:
Normal distribution:
mean μ₀ = 150
Sample:
Sample size n = 272
Sample mean x = 141
Sample standard deviation s = 66
The standard error of the sample mean SE = σ /√n
SE = 66/√272
SE = 66 / 16,49
SE = 4
Test Hypothesis:
Null hypothesis H₀ x = μ₀
Alternative hypothesis Hₐ x < μ₀
z(s) test statistics is:
z(s) = ( x - μ₀ ) / s/√n
z(s) = - 9 /4
z(s) = - 2,25
p-value for that z(s) p-value = 0,0122
Then for α = 0,05 p-value < 0,05
We are in the rejection region we need to reject H₀
Like I said on the other question. Slope will ALWAYS be the number beside x and y-intercept will always be after that.
Slope-intercept form = y = mx + b
Slope goes where m is and y-intercept goes where b is.
Hope this helps!
Answer:
x=21
Step-by-step explanation:
The two angles form a straight line so they add to 180
6x+2+52 = 180
6x+54= 180
Subtract 54 from each side
6x+54-54 = 180-54
6x= 126
Divide by 6
6x/6 =126/6
x = 21
