Calculate the area of the backyard

A=20(14)=280\ yd^{2}

step 2

Calculate the area of the flower garden

A=5(9)=45\ yd^{2}

step 3

Determine the difference

280\ yd^{2}-45\ yd^{2}=235\ yd^{2}

Zina [12379]

Answer:

The null hypothesis states that 48% of the healthcare provider's members received their flu shot.

The alternative hypothesis claims that the proportion of members who received their flu shot differs from 48%.

Step-by-step explanation:

A null hypothesis is a proposed statement regarding a population parameter that is tested for acceptance or rejection.

An alternative hypothesis presents a contradicting statement to the null hypothesis and is accepted when evidence disproves the null hypothesis.

Question 1(Multiple Choice Worth 2 points)
babunello [11817]
Here are 3 questions with their respective answers.

1) Find


\lim_{x \to \ 2^+} f(x)

Answer: 4.

Explanation:

This expression indicates the limit as the function f(x) approaches 2 from the right side.

You should apply the function (the line) from the right side of 2 and get as close to x = 2 as you can.

That line has an open circle at y = 4, which is the limit we are looking for.

2) Analyze the graph to see if the limit exists.

Answer:

\lim_{x \to \ 2^-} f(x) = 3

\lim_{x \to \ 2^+} f(x)=-3

To find each limit, utilize the function approaching from the direction of x.

It's important to note that since the two limits differ, it is concluded that the limit of the function as x approaches 2 does not exist.

3)
Answer: -1


\lim_{x \to \ 3^-} f(x) = -1

To determine the limit as the function approaches 3 from the left, follow the line ending with an open circle at (3, -1).

Hence, the limit is -1.

A box has 1 red marble, 3 blue marbles, and 4 green marbles. Maya draws a blue marble randomly from the box, replaces it, and th
Svet_ta [12734]

Response:

Sampling with replacement signifies that a marble is selected, its color is noted, replaced, and the box is shaken before another selection is made.\dfrac{9}{64}

There are 1+3+4=8 marbles in total. The probability of selecting the first blue marble is \dfrac{3}{8}., then when Maya places this marble back, the chance of picking the second blue marble remains constant. By applying the product rule, the probability of drawing 2 blue marbles consecutively is

\dfrac{3}{8}\cdot \dfrac{3}{8}=\dfrac{9}{64}.

How is shading a grid to show 1 tenth different from shading a grid to show 1 hundredth?
AnnZ [12381]
To illustrate 1 hundredth (or 1%) on a grid consisting of 100 units, shade only 1 unit. In contrast, to illustrate 1 tenth (or 10%), you would shade 10 units. A visual representation of the grid would be helpful for further explanation.
