The isosceles trapezium below has perimeter 28 m. Find x and y.

The sum of two numbers is -4.5. Six less than twice the value of the first number is equal to the second number. Find the number

elena-s [515]

Answer:

first is 3.5, second is 1

Step-by-step explanation:

-4.5 = x + 2x - 6

-4.5 - 6 = 3x

10.5 = 3x

10.5/3 = x

3.5 = x

2(3.5) - 6

7 - 6

Can someone please help me with this problem!

Anna71 [15]

Answer:

11 yards

Step-by-step explanation:

The volume of a cone formula is:

$V=\frac{1}{3}\pi r^2 h$

Where V is the volume,

r is the radius (half of diameter)

h is the height

Given,

h = 15

V = 475.17

We find the radius (r) first by substituting given values:

$V=\frac{1}{3}\pi r^2 h\\475.17=\frac{1}{3}\pi r^2 (15)\\475.17=5\pi r^2\\r^2=30.25\\r=5.5$

The radius (r) is 5.5 yards

We need the diameter, which is DOUBLE THE RADIUS, so diameter would be:

Diameter = 5.5 * 2 = 11 yards

bulgar [2K]

Answer

58,432 money you have leftover or $8,700 still left to pay.

Step-by-step explanation:

After knowing the contracts for steady work is 45 hours per week I just divided it by the days she works a week, which is most likely 5 and got 9 hours a day, then did $25 * 9 to get the payment per day which is $225 then multiplied it by 5 for the days working in a week, then multiply it again by 52 to get $58,500 as your payment and if your expenses is $5.6 per month (5.6*12=67.2) then your payment cover all of it and you still have $58,432.8 remaining, but if the expenses are $5,600 a month (5,600*12=67,200) then you cover most of it but still have to pay $8,700

At the Fidelity Credit Union, a mean of 7.1 customers arrive hourly at the drive-through window. What is the probability that, i

Sergio [31]

Answer:

The probability that, in any hour, less than 2 customers will arrive is 0.0067.

Step-by-step explanation:

The random variable X can be defined as the number of customers arriving hourly at the drive-through window at the Fidelity Credit Union.

The random variable X describes a finite number of occurrences of an event in a fixed time interval.

The random variable X follows a Poisson distribution with parameter λ = 7.1.

The probability mass function of X is:

$P(X=x)=\frac{e^{-7.1}(7.1)^{x}}{x!};x=0,1,2,3...$

Compute the probability of less than 2 customers arriving as follows:

$P(X$

$=\frac{e^{-7.1}(7.1)^{0}}{0!}+\frac{e^{-7.1}(7.1)^{1}}{1!}\\\\=0.00083+0.00586\\\\=0.00669\\\\\approx 0.0067$

Thus, the probability that, in any hour, less than 2 customers will arrive is 0.0067.
