Answer:
Yes it is safe
Step-by-step explanation:
lower bound of fred's weight (88kg) = 87.5kg
upper bound of total mass (480kg) = 567.5 kg
567.5kg - 87.5kg = 480 kg
The total mass in the lift after Fred gets out is [tex]477[/tex] kg which is less than the safe limit of [tex]480[/tex] kg. So, the lift is safe to use.
Maximum mass in the lift [tex]= 480[/tex] kg.
Total mass of Fred and other people in the lift [tex]= 565[/tex] kg.
Mass of Fred, in nearest kg, [tex]= 88[/tex] kg.
Fred gets out of the lift. So, subtract the mass of Fred from the total mass in the lift.
Total mass of people in the lift [tex]= 565-88 = 477[/tex] kg, which is less than safe limit of mass in the lift.
So, the lift is safe to use now.

If there are 22 successes in a sample with a size of 40, what is the sample
proportion?
A. 0.55
B. 0.65
C. 0.44
D. 0.22
Answer:
A
Step-by-step explanation:
22 successes out of a group of 40 means 22/40 were good. Now, simplify 22/40. Both can be divided by 2.
22/2 = 11
40/2 = 20
Now you have 11/20. Put this in decimal form and you have 0.55
Option A answer is 0.55
What is the proportion of a sample?The proportion of a sample is the ratio of the number of successes or defeats to the total size of the sample, it is used for understanding which trend is more followed and also has many uses in the real world.
The solution to the given problemThe size of the sample is 40.
There are 22 successes in the sample.
To find the proportion of success we have to find the ratio of 22 and 40 which is 11:20, and in numerical terms 0.55
Hence option A is correct, the proportion is 0.55

Particle x moves along the positive x-axis so that it's position at time t is less than equal to 0 is given by x(t)= 5t^3 - 9t^2 + 7. Is particle x moving toward the right at time t=1?
So, at [tex]t=\frac{6}{5}[/tex], the velocity changes towards the right.
Velocity:Velocity is the prime indicator of the position as well as the rapidity of the object. It can be defined as the distance covered by an object in a unit of time. Velocity can be defined as the displacement of an object in a unit of time.Given that,
[tex]x(t)=5t^{3} -9t^{2} +7[/tex]
[tex]{x}'\left ( t \right )=15t^{2}-18t \\ {x}'\left ( 1 \right )=15t-18 \\ =-3 < 0[/tex]
Therefore, the particle is moving towards the left.

Last week, an online site received $355.60 for selling 20 cell phone accessories Cell phone cases sell for $10.98 and Airpods sell for $27.98.
1. Define the variables.
2. Then, write the system of equations to model this situation.
Answer:
i. Cell phone cases
Airpods
ii. x + y = 20 .............. 1
10.98x + 27.98y = 355.60 .............. 2
iii. x = 12, and y = 8
Step-by-step explanation:
Amount of sale = $355.60
Cost of Cell phone cases = $10.98
Cost of Airpods = $27.98
Number of phone accessories sold = 20
1. The variables to be considered in the question are:
i. Cell phone cases
ii. Airpods
2. Let the number of cell phone cases bought be represented by x, and that of airpods be represented by y.
Thus,
x + y = 20 .............. 1
10.98x + 27.98y = 355.60 .............. 2
From equation 1,
x = 20 -y
substitute the value of x in equation 2
10.98(20 - y) + 27.98y = 355.60
219.6 -10.98y + 27.98y = 355.60
17y = 136.60
y = [tex]\frac{136.60}{17}[/tex]
y = 8.0353
So that,
x = 20 -y
= 20 - 8.0353
x = 11.9647
Thus,
x = 12, and y = 8

A walking track is 2 1/2 miles long. How many feet is that?
Answer:
13,200 feet
Step-by-step explanation:
Answer:
13,200 feet
Step-by-step explanation:
In one mile, there are 5,280 feet.
You're trying to find how many feet are in 2.5 miles, so you can set up a proportion.
X = the number of feet in 2.5 miles.
[tex]\frac{1 mile }{5280 feet} = \frac{2.5 miles}{X feet}[/tex]
To find X, all you need to do is cross multiply.
So,
X = 5280 × 2.5 = 13,200 feet
