Answer:
65 ride tickets would cost $39
Step-by-step explanation:
so
12 ÷ 20 = 0.6 <em>(I checked it by multiplying 0.6 by 20 to get 12)</em>
0.6 × 60 = 39
65 tickets would cost $35
I'm pretty sure it's 29 . . . A way to remember is that when you multiply a number by ten, add a zero. For example, 34 x 10 is 340. Just add the zero!
Answer:
−0.42x^3 −6.45x
Step-by-step explanation:
Answer:(c)
Step-by-step explanation:
Given : In a hypothesis testing the null hypothesis has been rejected when the alternative hypothesis has been true.
Find : to find that the given decision is create type I error , type II error or right decision has been taken
Step by step :
In hypothesis testing there are 2 types of error.
(1)Type I error :- if the null hypothesis is rejected when it is true, is known has Type I error .
(2)Type II error:- if the null hypothesis is accepted when alternative hypothesis is true, is known as type II error.
Since here null hypothesis has been rejected when alternative hypothesis has been true,i.e., the correct decision has been made
Hence option (c) is correct.
The first solution involves the volume of a pyramid. With the parameters, the volume is given as: 51cm³
<h3>What is the Volume of a Pyramid?</h3>
The volume of a pyramid is given as:
V = (lwh)/3
Where:
- L = base length
- w = base width
- h = pyramid height.
Hence, the volume of the pyramid is given as:
(6 x 5.2 x 4.9)/3
= 152.88/3
= 50.96
≈ 51 cm³
<h3>
What is the volume of the juice container?</h3>
Assuming that it is a cuboid, the volume for the shape of a cuboid is given as:
L x B x H
Where:
L = Length = 2cm
B (Width) = 34cm
H = Height = 12.2
Hence the Volume =
2 x 34 x 12.2
= 829.6
≈ 830 cm³
<h3>
What is the volume of the pit?</h3>
We are not given it's geometric description so we assume that it is a Cuboid.
Recall that the Volume of a Cuboid = L x B x H
Hence the Volume of the pit is:
7 x 5 x 8
<h3>
= 280 cm³
How much space can a box that measures 50cm on each edge hold?
</h3>
From the question, we can infer that we are dealing with a Cube.
The volume of a cube is given as L³.
Recall that L = 50cm
Hence, the volume is = 50³
= 125,000 cm³
<h3>
What is the volume of a rectangular prism?
</h3>
The formula for the volume of a rectangular prism is:
L x W x H; where
L (Length) = 130cm
W (Width) = 70cm
H (Height) = 110cm
→ 130 x 70 x 110
= 1,001,000 cm³
