Answer: We reject the null hypothesis.

Step-by-step explanation:

Given : Significance level : \alpha=0.01

Let p represents the proportion of the settled medical malpractice suits.

Given claim : The percentage of settled medical malpractice suits is at least 50%.

i.e. p\geq 0.5

Thus,

H_0:p\geq0.5\\\\H_a:p

We know that when the calculated p-value is less than the significance level (\alpha) then we reject the null hypothesis, if p-value is greater than the significance level (\alpha) then we do not reject.

Now , the calculated value 0.012 is less than the 0.01, so we reject the null hypothesis.

A landscaper receives a discount on each plant purchased. The original price of each plant is x dollars. The landscaper purchase
prisoha [69]

Answer:

$4

Step-by-step explanation:

Discount is a form of consideration in price or amount given to a customer on a sale of goods. It can be deduced from the question that;

The original price of each plant = $x

Number of plants purchased = 20

Price of the number of plants purchased without discount = $20x

Amount paid for the 20 plants with discount = $(20x - 80)

Thus,

The discount on the 20 plants = $80

Discount on each plant = \frac{total discount on plants}{number of plants purchased}

                                       = \frac{80}{20}

                                       = $4

Discount on each plant = $4

Therefore, each plant was discounted by $4.

Answer:

SA = 52 square meters

Step-by-step explanation:

<em>First, the equation I'll be using for this problem is</em><em> SA=2(wl+hl+hw)</em><em>! Our </em><em>width is 4m, </em><em>our </em><em>length is 3m</em><em>, and our </em><em>height is 2m</em><em>. To begin to solve this problem we are going to input these values in to the equation above.</em>

SA = 2(4 × 3 + 2 × 3 + 2 × 4)

<em>Next, we are going to multiply our values inside the parenthesis based on the </em><em>PEMDAS</em><em> </em><em>strategy</em><em> (if you have any questions about this, feel free to ask below :).</em>

SA = 2(12 + 6 + 8)

<em>Now, we can add our values inside the parenthesis.</em>

SA = 2(26)

<em>Finally, all we have to do is distribute the 2 outside of the parenthesis to inside the parenthesis.</em>

SA = 52 square meters

<em />

Hope this Helps! :)
