Answer:
False
Step-by-step explanation:
The sequence seems to be increasing by 3+3(-5+3=-2, -2+3+3=4, so on). By 13, the sequence is increasing by 11, making the next number 24.
Answer:
Step-by-step explanation:
Perimeter of a rectangle = 2L +2W
L is the length
W is the width
If the length of a rectangle is 2 cm less than 7 times the width, then;
L = 7W-2 .... 2
Substitute eqn into the formula for finding the perimeter
P = 2(7W-2)+2W
P = 14W-4+2W
P = 16W-4
If P =60cm
60 = 16W-4
16W = 60+4
16W = 64
W = 64/16
W = 4cm
Hence the width of the rectangle is 4cm
Since l = 7w-
l = 7(4)-2
L = 28-2
L = 26cm
You can proceed and draw a rectangle with the dimension of 4cm by 26cm
Answer:
Not independent
Step-by-step explanation:
The number of single bedroom apartments is 90;
The number of single occupants in that 90 is 64;
64/90 or 32/45 is the rate that a single occupant lives in a 1 bedroom apartment.
The number of multiple bedroom apartments is 110;
The number of single occupants in that 110 is 12;
12/110 or 6/55 is the rate that a single occupant lives in a multiple-bedroom apartment.
The rate of single occupants in any type of apartment is 76/200 or 19/50
32/45>19/50>6/55; since the rate of single occupants in 1 bedroom apartments is higher than the rate of single occupants living in any type of apartment and a multiple-room apartment, the event that an apartment has 1 bedroom and 1 occupant is not indepenent.
Answer: T = 4
Step-by-step explanation:
1. Write all the variables down
P = 8 V = 2X N = 2 R = 2X X = 3
2. Since you know that X = 3 substitute it in to find V and R
V = 2X = 2(3) = 6
R = 2X = 2(3) = 6
3. Find PV
PV = P x V
= 8 x 6
= 48
4. Find NRT
NRT = N x R x T
= 2 x 6 x T
= 12 x T
= 12T
5. Find T
PV = NRT
48 = 12T
12T = 48
divide both sides by 12
T = 48 ÷ 12
T = 4
Experimental value=13.2mL
actual volume=13.7mL
|13.2-13.7|=|-0.5|=0.5
0.5/13.7 *100%=3.7%
