Y=2x+1 would be the linear function
Answer:
7.23522974
Step-by-step explanation
7 would be in the ones place, 2 in the tenths, 3 in the hundredth, 5 in the thousandth, and so on. Since the number after 3 is over 5, it will go up by one. So the answer would be 7.23522974
Answer:
38°
Step-by-step explanation:
All triangles have a sum of 180°
180 - (119 + 23) = missing angle
180 - (142) = missing angle
38 = missing angle
So, the missing angle has a measurement of 38°
Step-by-step explanation:
x=y+7
3x+2y=6
so wherever you see X you but y+7
3(y+7)+2y=6
3y+21+2y=6
group like terms
3y+2y=6-21
5y=-15
divide by 5
y=-3
to find x sub the y value in the equation
x=y+7
x=-3+7
x=4
The bell curve attached below shows the normal distribution of the data.
We are looking the value of X such as the area to its left gives the probability of 0.75
We first need the z-score which we can obtain by reading from the z-table (as shown in the second picture below)
The z-score is = 0.7734
Then we use the following formula to work out X
z-score = (X - Mean) ÷ Standard Deviation
0.7734 = (X - 100) ÷ 15
0.7734×15 = X - 100
11.601 = X - 100
X = 11.601 + 100
X = 111.601 ≈ 112
Hence the third quartile is 112
