Answer:

The volume of container is 2 ft ³.

Step-by-step explanation:

We have,

Length = 1 ft .
Breadth = 1 ft.
Height = 2 ft.

We have Formula, Volume of Cuboid.

$\small \sf \mapsto \: Volume = length × breadth × height$

substitute the values

$\small \sf \mapsto \: Volume = 1 ft × 1 ft × 2 ft$

multiply the values

$\small \sf \mapsto \: Volume = 2 \: ft {}^{3}$

Hence, the volume of container is 2 ft ³.

Answer:

2 $ft^{3}$

Step-by-step explanation:

volume of a cuboid = length * breadth * height

= 2*1*1

=2 $ft^{3}$

A lawn service owner is testing new weed killers. He discovers that a particular weed killer is effective 89% of the time. Suppo

Answer:

The 90% confidence interval for p is (0.8236, 0.9564). The upper confidence limit for p is 0.9564.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

He discovers that a particular weed killer is effective 89% of the time. Suppose that this estimate was based on a random sample of 60 applications.

This means that $\pi = 0.89, n = 60$

90% confidence level

So $\alpha = 0.1$ , z is the value of Z that has a pvalue of $1 - \frac{0.1}{2} = 0.95$ , so $Z = 1.645$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.89 - 1.645\sqrt{\frac{0.89*0.11}{60}} = 0.8236$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.89 + 1.645\sqrt{\frac{0.89*0.11}{60}} = 0.9564$

The 90% confidence interval for p is (0.8236, 0.9564). The upper confidence limit for p is 0.9564.

Help me with thiqs one please

Vedmedyk [2.9K]

Answer:

Step-by-step explanation:

for x= -4

h(x)= 4(-4) + 4

= -12+4

= -8

for x= -2

h(x)= 4(-2) + 4

= -8+4

= -4

for x=1

h(x)= 4(1) + 4

for x=3

h(x)= 4(3) + 4

=12+4

=16

for x=5

h(x)= 4(5) + 4

=24

The frosty ice cream shop sells sundaes for $2 and banana splits for $3. On a hot day the shoot sold 8 more sundaes than banana

sashaice [31]

Let’s designate the number of banana splits sold as x. That means the number of sundaes sold is x + 8.

Now if we put this into an equation, also keeping in mind their costs, we get:
3(x) + 2(x + 8) = 156

Now to solve for x:
3x + 2(x + 8) = 156
3x + 2x + 16 = 156
5x = 140
x = 28

That means you’ve sold 28 banana splits and 36 sundaes! :)

20 points plus that brain thing

madam [21]

Answer:

$\huge\boxed{\sf \$ \ 26.24}$

Step-by-step explanation:

Each side of the squared painting = 41 inches

A square has 4 sides. So,

4 sides of the square painting = 4(41) inches

= 164 inches

$\rule[225]{225}{2}$

<u>The shop charges:</u>

1 inches = $ 0.16

Multiply both sides by 164

164 inches = $ 0.16 × 164

164 inches = $ 26.24

$\rule[225]{225}{2}$

Hope this helped!
