The average of 4 numbers is 9. If one of the numbers is 7, What is the sun of the other 3 numbers?
Answer:
Step-by-step explanation:
Comment
If 4 numbers have an average of 9, then total of the 4 numbers is 4 * 9 = 36.
If one of the 4 numbers is a 7, then
7 + x = 36 where x is the sum of the other 3 numbers.
7 + x = 36 Subtract 7 from both sides
7- 7 +x = 36 - 7
x = 29

Ahmed is three times as old as Suad. Deeqa is three times o Ahmed. If Deeqa is 39 years old. How old is Suad?
Answer:
Suad is 4.333 years old.
Step-by-Step explanation:
let x = Suad's age
let y = Deeqa's age
let z = Ahmed's age
y = 3x
z = 3y = 3(3x)
but z = 39
3(3x) = 39
x = 4.33333
a water tank is empty. Anil needs to fill the tank with 2400 litres of eater
Answer:
2400 liters in tank
Step-by-step explanation:
Company A would take 260 minutes more than Company B for filling 2400 liters of water in Anil's tank when the rate at which Company A fills is 8 liters in 1 minute and 40 seconds, while the rate at which Company B fills is 2.2 gallons per minute.
What is the meaning of rate?Rate is the ratio of quantity to time.
[tex]RATE = \frac{QUANTITY}{TIME}[/tex].
How to solve the question?In the question, we are asked to find the time which Company A takes more than Company B for filling a water tank of 2400 liters when Company A fills water at a rate of 8 liters in 1 minute and 40 seconds, while the rate at which Company B fills is 2.2 gallons per minute.
For Company A:
The capacity of the tank = 2400 liters
Rate = 8 liters in 1 minute and 40 seconds
Now, 1 minute and 40 seconds = 1 + 40/60 minutes = 1.67 minute
Therefore, the actual rate = 8/1.67 = 4.8 liters per minute.
Therefore, the time taken by Company A = 2400/4.8 minutes = 500 minutes.
For Company B:
The capacity of the tank = 2400 liters.
We know 1 gallon = 4.54 liters,
or, 1/4.54 gallons = 1 liter.
Therefore, the capacity of the tank = 2400 * (1/4.54) gallons = 528.634 gallons.
Rate = 2.2 gallons per minute.
Therefore, the time taken by Company B = 528.634/2.2 minutes = 240.288 minutes.
Therefore, the time that Company A takes more than Company B = 500 - 240.288 minutes = 259.712 minutes ≈ 260 minutes.
The given question is an incomplete question. The complete question is:
"A water tank is empty.
Anil needs to fill the tank with 2400 liters of water.
Company A supplies water at a rate of 8 liters in 1 minute and 40 seconds.
Company B supplies water at a rate of 2.2 gallons per minute.
1 gallon = 4.54 liters.
Company A would take more time to fill the tank than Company B would take to fill the tank.

A confidence interval is a range of estimates for an unknown parameter in frequentist statistics. The 95 percent confidence level is the most common, but other levels, like 90 percent or 99 percent, are occasionally used when computing a confidence interval.
Given in a test of effectiveness of garlic for lowering cholesterol, 50 subjects were treated with garlic in a processed tablet form.Both before and after the therapy, cholesterol levels were assessed.
LDL cholesterol variations had a mean of 4.4 and a standard deviation of 19.4 (in mg/dL). The best point estimate is 4.4.
We have to find 95% confidence interval estimate of the population mean
So,

What is the horizontal and vertical shift for the absolute value function below f(x)=3[x+9]+6
We will see that we have a shift of 9 units to the left and 6 units upwards
How to identify the translations?For any given function H(x), we define a vertical shift of N units as:
g(x) = H(x) + N.
If N > 0, the shift is upwards.If N < 0, the shift is downwards.While a horizontal shift is written as:
g(x) = H(x + N).
If N > 0, the shift is to the left.if N < 0, the shift is to the right.Here we know that:
f(x) = 3*|x + 9| + 6
If the original function was:
H(x) = 3*|x|
Then we can write:
f(x) = H(x + 9) + 6

A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. The probability that none of the LED light bulbs are defective is 0.2213.
What is Binomial distribution?A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,
P(x) = ⁿCₓ (pˣ) (q⁽ⁿ⁻ˣ⁾)
Where,
x is the number of successes needed,
n is the number of trials or sample size,
p is the probability of a single success, and
q is the probability of a single failure.
Given the probability of a bulb being a failure is 14%, therefore, the probability of bulb passing the quality check is 86%.
Let the probability of success be defined as 0.14 for binomial distribution, and the probability for failure be 0.86. Therefore, The probability that none of the LED light bulbs are defective is
P(x=0) = ¹⁰C₀ (0.14)⁰ (0.86)¹⁰ = 0.2213

Find all (a, b, c, d) in R4
such that the given set is orthogonal.

Answer:
[tex]\left[\begin{array}{}0&\\1&\\-2&\\1&\end{array}\right][/tex] t in R Correct option (B)
Step-by-step explanation:
Orthogonal vectors : We say that 2 vectors are orthogonal if they are perpendicular to each other. i.e. the dot product of the two vectors is zero.
Dot product : The dot product of two vectors is equal to the sum of the products of the individual components of the two vectors.
for the given vector (a, b, c, d) to be orthogonal its dot product with each vector must be 0
therefore (1, 2, 1, 0).(a, b, c, d) = 0
a + 2b+ c+ 0 = 0 -------- (i)
similarly (1, -1, 1, 3 ).(a, b, c, d) = 0
a - b + c + 3d = 0 -------- (ii)
(2, -1, 0, 1).(a, b, c, d) = 0
2a - b + 0 + d = 0 ---------- (iii)
subtracting equation (i) from (ii)
a - b + c + 3d - a - 2b - c - 0 = 0
-3b + 3d = 0
b = d
substituting b = d in (iii)
2a + b + 0 + b = 0
2a + 2b = 0
a = 0
substituting a = 0 , b = d in (i)
0 + 2d + c + 0 = 0
c = -2d
thus for any t ∈ R, vector(0, t, -2t, t) will make the given set orthogonal
the above vector can also be written as (0, 1, -2, 1)

The graph below have the same shape. What is the equation of the red graph
Answer:
G(x)=x³-1
because it intersect at the negative side of y
Answer:
g(x) = x³ - 1
(option C)
Step-by-step explanation:
We know that the shape of the graph has not changed, as stated in the question, meaning that the change has not happened as a direct change to x (like 2x³ instead of x³).
The entire graph has been moved down and not left/right, which would have happened inside the parenthesis (like g(x) = (x³ - 3)).
Because it has been shifted down (as evident by the y-intercept), and we know that the shape has not changed, we know that the original function was shifted down 1 --which can be expressed by the equation g(x) = x³-1
