1 kg= 1000g
threfore 100g=100/1000 kg
=0.1 kg
95p= 1/2 kg ...1/2 kg=0.5 kg
; 0.5=95
0.1=? ; (0.1*95)/0.5
=19p
Since that is a straight line, our equation is 6x = 180
Solving, we have x = 30
Answer:
y = 0.75x + 2 ft
x = 24 yrs
Step-by-step explanation:
slope is (9/12) = 0.75 ft/yr
Y intercept is original height of tree 5 - 4(0.75) = 2 ft
y = 0.75x + 2
20 = 0.75x + 2
18 = 0.75x
x = 24 yrs
Answer:
91% of the time the auto will get less than 26 mpg
Step-by-step explanation:
Think of (or draw) the standard normal curve. Mark the mean (22.0). Then one standard deviation above the mean would be 22.0 + 3.0, or 25.0. Two would be 22.0 + 2(3.0), or 28.0. Finallyl, draw a vertical line at 26.0.
Our task is to determine the area under the curve to the left of 26.0.
Using a basic calculator with built-in statistical functions, we find this area as follows:
normcdf(-100, 26.0, 22.0, 3.0) = 0.9088, which is the desired probability: 91% of the time the auto will get less than 26 mpg.
Answer:
please last option
using 45 degree as reference angle
using tan relation
Tan45=perpendicular /base
1 = x\6
x = 6
now using right angled triangle relation
H²=p²+b²
then h²= 6²+6²
H = √36+36
H =6√2
therefore y=6√2
