Answer:
x>-2
Step-by-step explanation:
-3x+2<8
Subtract 2 from each side
-3x+2-2<8 -2
-3x < 6
Divide each side by -3. remembering to flip the inequality
-3x/-3 >6/-3
x>-2
Answer:
The area under the standard normal curve to the left of z=−2.94 and to the right of z=−2.28 is 0.9903 square units.
Step-by-step explanation:
We need to find the area under the standard normal curve to the left of z=−2.94 and to the right of z=−2.28.
The standard normal table represents the area under the curve.
.....(1)
According to the standard normal table, we get
Substitute these values in equation (1).
Therefore the area under the standard normal curve to the left of z=−2.94 and to the right of z=−2.28 is 0.9903 square units.
Answer:
median=17, mean=20.5
Step-by-step explanation:
so for the median its best to organize in chronological order. 4,6,6,28,39,40 and to find the value do (6+28)/2=17
for mean just add all the numbers up and divide by 6. 123/6 =20.5
Answer:
x=-3/2
Step-by-step explanation:
-3(x+2)+5x=-9
-3x-6+5x=-9
2x-6=-9
2x=-9+6
2x=-3
x=-3/2
Answer:
m<Q = 92 degrees
Step-by-step explanation:
Opposite angles of a quadrilateral inscribed in a circle are supplementary.
Angles O and Q are opposite angles, so they are supplementary, so their measures add up to 180 degrees.
m<O + m<Q = 180
2x + 2x + 4 = 180
4x + 4 = 180
4x = 176
x = 44
m<Q = 2x + 4 = 2(44) + 4 = 92
