Michael is planting a garden in the shape of a right triangle. He wants 4 tickseed plants for each square meter of area. How man

Paladinen [302]

Answer:

336 plants

Step-by-step explanation:

To find the number of tickseed plants that Michael needs to plant in his garden, we have to find the area of the garden first.

We notice that the garden has the shape of a right triangle: so, we have to find the area of the right triangle.

The area of a triangle is given by the formula

$A=\frac{1}{2}bh$

where

A is the area

b is the length of the base

h is the height of the triangle

From the figure, we see that:

b = 7 m is the length of the base

h = 24 m is the height of the triangle

Therefore, applying the formula, we find the area of the garden:

$A=\frac{1}{2}7\cdot 24 =84 m^2$

We also know that Michael wants to plant 4 tickseed plants for each square meter of area; therefore, the total number of plants that Michael will plant is 4 times the area of the garden, so:

$N=4A=4\cdot 84=336$

Type a digit that makes this statement true.<br><br> 768,72<br> is divisible by 6.<br><br> Help Me

kiruha [24]

Answer:

6

Step-by-step explanation:

Rule for divisibilty of 6:

sum of place values is a multiple of 3
an even number

Step 1: dd the integers

7 + 6 + 8 + 7 + 2 + x
30 + x

Now, we have a couple options:

x = 3
x = 6
x = 9

You can use any of these three values,

But the number has to be even, so the last digit has to be even. The correct answer is 6.

Suppose that the hourly wages of fast food workers are normally distributed with an unknown mean and standard deviation. The wag

Nutka1998 [239]

Answer: 1.303639

Step-by-step explanation:

The t-score for a level of confidence $(1-\alpha)$ is given by :_

$t_{(df,\alpha/2)}$ , where df is the degree of freedom and $\alpha$ is the significance level.

Given : Level of significance : $1-\alpha:0.80$

Then , significance level : $\alpha: 1-0.80=0.20$

Sample size : $n=40$

Then , the degree of freedom for t-distribution: $df=n-1=40-1=39$

Using the normal t-distribution table, we have

$t_{(df,\alpha/2)}=t_{39,0.10}=1.303639$

Thus, the t-score should be used to find the 80% confidence interval for the population mean =1.303639
