Answer:
The raw score for his exam grade is 99.69.
Step-by-step explanation:
Given : The professor announced that the mean for the class final exam was 88 with a standard deviation of 7. Given Daniel's z score of 1.67.
To find : What is the raw score for his exam grade?
Solution :
The formula use to find the z-score is
Where, z=1.67 is the z-score
is the means
is the standard deviation
x is the raw score for his exam grade
Substitute the values,
Therefore, the raw score for his exam grade is 99.69.
Answer:
y > 4x + 1
Step-by-step explanation:
Equation of the dotted line:
Slope = (-3-1)/(0-1) = 4
Y intercept is +1
y = 4x + 1
Shaded region:
y > 4x + 1
Answer:
-1/5>-10/4
Step-by-step explanation:
In the negatives, If you take away the negative the lower number is more.
Think about a number line, if you are at -1/5, it means that you are 1/5 away from 0. If you are at -10/4, It means that you are 10,4 away from 0.
In conclusion, -1/5>-10/4
pls mark Brainliest
Take half of the coefficient of x: It is 3, and half that is 3/2.
Then <span>x^2+3x=6 becomes:
</span><span> x^2+3x + (3/2)^2 =6 + (3/2)^2, and
(x+3/2)^2 = 6 + 9/4
You were not asked to solve the equation, but why not do it for the practice?
</span>Solve (x+3/2)^2 = 6 + 9/4 for x. There will be 2 values.
Y I believe equals 8 I hope I helped
Brainliest would be nice:) :)
