$30 bat; 15% discount

1 answer:

8 0

Multiply $30 by 0.15 to find the amount discounted:
30x0.15=$4.50

Now subtract 4.5 from 30 to find the final cost of the bat.
30-4.5= $25.50

Blue's Berry Farm charges Percy a total of

kaheart [24]

Answer:

The price for each kilogram of strawberries is $7.50

Step-by-step explanation:

The question is

Blues berry farm charges Percy a total of $24.75 for entrance and 2.5 kilograms of strawberries. The entrance fee is $6 and the price for each kilogram of strawberries is constant

Determine the price for each kilogram of strawberries

Let

x ----> the price for each kilogram of strawberries

we know that

The entrance fee plus the price of each kilogram of strawberries multiplied by the number of kilogram of strawberries must be equal to $24.75

The linear equation that represent this situation is

$2.5x+6=24.75$

solve for x

subtract 6 both sides

$2.5x=24.75-6\\2.5x=18.75$

divide by 2.5 both sides

$x=\$7.50$

therefore

The price for each kilogram of strawberries is $7.50

N triangle xyz, m∠z > m∠x m∠y. which must be true about △xyz?

liubo4ka [24]

The choices are the below that can be found elsewhere:

m∠X + m∠Z < 90°

m∠Y > 90°

∠X and∠Y are complementary

m∠X + m∠Y < 90°

Since the given is m<Z > m<X +m<Y and the sum of measure of angles of a triangle is equal 180 degrees so from this result that the last one choice need being true sure so m<X +m<Y < 90°

What is the first term of the expression? −6xyz + 9xy + 12x + 18y TIA!

tatyana61 [14]

For this case we have that by definition:

The terms of a polynomial expression are those that are composed of coefficients and variables separated by signs of addition and subtraction.

We then have the following expression:

$-6xyz + 9xy + 12x + 18y$

According to the definition, we can conclude that the first term is given by:

$-6xyz$

Answer:

The first term of the expression is:

$-6xyz$

Let X represent the amount of time until the next student will arrive in the library parking lot at the university. If we know t

Ber [7]

Answer:

The probability that it will take more than 10 minutes for the next student to arrive at the library parking lot is 0.0821.

Step-by-step explanation:

The random variable X is defined as the amount of time until the next student will arrive in the library parking lot at the university.

The random variable X follows an Exponential distribution with mean, μ = 4 minutes.

The probability density function of X is:

$f_{X}(x)=\lambda e^{\lambda x};\ x\geq 0, \lambda >0$

The parameter of the exponential distribution is:

$\lambda=\frac{1}{\mu}=\frac{1}{4}=0.25$

Compute the value of P (X > 10) as follows:

$P(X>10)=\int\limits^{\infty}_{10}{0.25e^{-0.25x}}\, dx$

$=0.25\times \int\limits^{\infty}_{10}{e^{-0.25x}}\, dx\\=0.25\times |\frac{e^{0.25x}}{-0.25}|^{\infty}_{10}\\=(e^{-0.25\times \infty})-(e^{-0.25\times 10})\\=0.0821$

Thus, the probability that it will take more than 10 minutes for the next student to arrive at the library parking lot is 0.0821.
