Answer:
n=-2
Step-by-step explanation:
4n+12=4
-12 -12
4n=-8
4n÷4=-8÷4
n=-2
Hi there!
If Jeremy walked 6/8 of the way to school and ran the rest we know that Jeremy ran 2/8 of the way. We can simplify this further to get to our simplest form.
6/8 ---> 3/4 Simplified.
So your answer is Jeremy walked 3/4 of the way.
Answer:
a = 35, b = 40, c = 17.5
Step-by-step explanation:
The sum of the 3 arcs on the semicircle above the diameter = 180° , that is
65 + 80 + a = 180
145 + a = 180 ( subtract 145 from both sides )
a = 35
The inscribed angles b and c are half the measures of their intercepted arcs
b = 
× 80 = 40
c = × 35 = 17.5
Answer: 35.
Step-by-step explanation: The parenthesis with no operation in between is multiplication. double negative makes a positive so its 7 times 5 which is 35.
Answer:
P (z) = -1.5094
Step-by-step explanation:
We have to find P-value (that means we have to calculate the test value to evaluate a proportional hypothesis
From problem statement
P₀ = 0,44 44 % from publisher report
The claim :
350 = n random sample
P = 0,40 40 %
To calculate P value
P ( z ) = ( P - P₀ ) / √(P₀*Q₀)/n
then P ( z ) = - 0.04 / √(0,44)(0,56)/350 P(z) = - 0.04/0,02
P (z) = -1.5094
