The height of a door will be around 6 feet and 8 inches, so about 7 feet. You will need to convert this to meters. To do this, you should first know that 1 meter = 3.28 feet. Now, divide 7 by 3.28:
7/3.28 = 2.134
So, a reasonable estimate would be 2 meters.
Answer:
3.6669
Step-by-step explanation:
Given is a frequency distribution and we are expected to find the mean of the distribution.
Let X be the no of total pets owned and f be the number of adults owning those pets.
Total
x 1 2 3 4 5 6 7
F 248 567 1402 728 419 456 203 4023
x*f 248 1134 4206 2912 2095 2736 1421 14752
Mean 3.666915237
Thus we find the total of all frequencies and then sum of product of x*f.
Mean = sum of f*x/sum of x
Here mean= 3.6669
Answer:
See below
Step-by-step explanation:
Direct variation means that changes in x will result to changes in y. If x increase, y also increases and vice versa.
y = kx
k = y / x
y = 45 ; x = 40
k = 45/40
k = 1.125
y = 1.125x
y will increase by 1.125 interval of x.
Let's solve your equation step-by-step.
4(2x+8)=10x+2−2x+30
Step 1: Simplify both sides of the equation.
4(2x+8)=10x+2−2x+30
(4)(2x)+(4)(8)=10x+2+−2x+30(Distribute)
8x+32=10x+2+−2x+30
8x+32=(10x+−2x)+(2+30)(Combine Like Terms)
8x+32=8x+32
8x+32=8x+32
Step 2: Subtract 8x from both sides.
8x+32−8x=8x+32−8x
32=32
Step 3: Subtract 32 from both sides.
32−32=32−32
0=0
Answer:
All real numbers are solutions.
