Answer:

Strawberries sold 44 baskets

Raspberries sold 52 baskets

Step-by-step explanation:

$4x + 9y = 644 \\ x + y = 96 \\ 4x + 4y = 384 \\ 5y = 260 \\ y = 52 \\ x = 44$

Answer: 44 baskets of strawberries were sold.

Step-by-step explanation:

Let x represent the number of basket of strawberries that were sold.

Let y represent the number of basket of raspberries that were sold.

In one morning, Katya sells 96. This means that

x + y = 96

At Katya’s fruit stand, a basket of strawberries costs $4 and a basket of raspberries costs $9. The total amount gotten from all the baskets sold is $644. It means that

4x + 9y = 644 - - - - - - - - - - - -1

Substituting x = 96 - y into equation 1, it becomes

4(96 - y) + 9y = 644

384 - 4y + 9y = 644

- 4y + 9y = 644 - 384

5y = 260

y = 260/5 = 52

x = 96 - y = 96 - 52

x = 44

Find the minimum point for the function f(x) = |2x - 1| (0, ½) (½, 0) (0, -½) (-½, 0)

torisob [31]

Minimum point of an absolute value function is when f(x) = 0
0 = |2x - 1|
2x - 1 = 0
2x = 1
x = 1/2

Minimum point is (1/2, 0)

Let X denote the distance (m) that an animal moves from its birth site to the first territorial vacancy it encounters. Suppose t

andrezito [222]

Answer and Step-by-step explanation: For an exponential distribution, the probability distribution function is:

f(x) = λ. $e^{-\lambda.x}$

and the cumulative distribution function, which describes the probability distribution of a random variable X, is:

F(x) = 1 - $e^{-\lambda.x}$

(a) Probability of distance at most 100m, with λ = 0.0143:

F(100) = 1 - $e^{-0.0143.100}$

F(100) = 0.76

Probability of distance at most 200:

F(200) = 1 - $e^{-0.0143.200}$

F(200) = 0.94

Probability of distance between 100 and 200:

F(100≤X≤200) = F(200) - F(100)

F(100≤X≤200) = 0.94 - 0.76

F(100≤X≤200) = 0.18

(b) The mean, E(X), of a probability distribution is calculated by:

E(X) = $\frac{1}{\lambda}$

E(X) = $\frac{1}{0.0143}$

E(X) = 69.93

The standard deviation is the square root of variance,V(X), which is calculated by:

σ = $\sqrt{\frac{1}{\lambda^{2}} }$

σ = $\sqrt{\frac{1}{0.0143^{2}} }$

σ = 69.93

Distance exceeds the mean distance by more than 2σ:

P(X > 69.93+2.69.93) = P(X > 209.79)

P(X > 209.79) = 1 - P(X≤209.79)

P(X > 209.79) = 1 - F(209.79)

P(X > 209.79) = 1 - (1 - $e^{-0.0143*209.79}$ )

P(X > 209.79) = 0.0503

P(X≤m) = 0.5

$\int\limits^m_0 f({x}) \, dx$ = 0.5

$\int\limits^m_0 {\lambda.e^{-\lambda.x}} \, dx$ = 0.5

$\lambda.\frac{e^{-\lambda.x}}{-\lambda}$ = $-e^{-\lambda.x} + e^{0}$

$1 - e^{-\lambda.m}$ = 0.5

$-e^{-\lambda.m}$ = - 0.5

ln( $e^{-0.0143.m}$ ) = ln(0.5)

-0.0143.m = - 0.0693

m = 48.46

A farmer has a rectangular field that is 100 yards long by 20 yards wide. What is the total area of the field?

sveta [45]

The area of the field is equal to the area of rectangular
a = l × w

Given:
l = 100 yards
w = 20 yards

Solution:
put the numbers to the formula
a = l × w
a = 100 × 20
a = 2,000
The area of the field is 2,000 square yards
