X=22
y=3
Pardon if I am wrong, but all you do is divide 172/8 then divide that by 6. Good Luck.
Answer:
can you show a picture
Step-by-step explanation:
it depends on the situation and the problem but normally you would use the other numbers to figure out what number goes in "x"
Answer:
9 units
Step-by-step explanation:
The distance from the car to the cabana is 3 units, and the distance from the cabana to the beach is 6 units. When measuring distance on a graph make sure to use absolute value, because distance can't be a negative number.
Answer:
The probability is 0.8944
Step-by-step explanation:
The probability of Z<1.25 in a normal distribution is
P(Z<1.25) = 0.5 + P(Z<1.25)
P(Z<1.25) = 0.5 + 0.3944
P(Z<1.25) = 0.8944
Hence, the probability of randomly selecting a z-score less than z = 1.25 from a normal distribution is 0.8944
Answer: Yes
Step-by-step explanation:
We will assume that each bulb is of 100 kW (kilowatt).
We will calculate how much energy in kilowatt-hours the light bulb will use per year in kilowatts, by the number of hours in a year.
We have, 100 kW = 0.1 kW so the energy consumed in one year is,
0.1 \times 8760=876.0\text {kWh} Since there are 8760 hours in one year. It is given that there are 9 bulbs so we need to have, 876 \times 9 = 7884 \text {kWh}
It is given that 1 ton of coal produces 2460 kWh, so 4 tons of coal will produce, 4\times 2460= 9840 \text {kWh}
We can observe that 4 tons of coal is producing 9840 kWh which is mroe than 7884 kWh. So, yes, 4 tons of coal can produce enough power to light 9 bulbs for a year
