If Mr. Giordano's drove 4.5 miles in 5 minutes and Mr. Baras drove 6.3 miles in 8 minutes, then the Mr. Giordano drove fast because speed of Mr. Giordano is greater than Mr. Baras
The distance traveled by Mr. Giordano = 4.5 miles
The time taken = 5 minutes
Speed = Distance / Time
Substitute the values in the equation
Speed = 4.5/5
= 0.9 miles per minutes
The distance traveled by Mr. Baras = 6.3 miles
The time taken = 8 minutes
Speed = Distance / Time
Substitute the values in the equation
Speed = 6.3/8
= 0.78 miles per minutes
Hence, if Mr. Giordano's drove 4.5 miles in 5 minutes and Mr. Baras drove 6.3 miles in 8 minutes, then the Mr. Giordano drove fast because speed of Mr. Giordano is greater than Mr. Baras

=============================================================
Explanation:
For triangles ABC and DEF we have these two pairs of congruent sides
AB = DE = 7BC = EF = 12In between sides AB and BC is angle ABC = 82
In between sides DE and EF is angle DEF = 2x-6
Since AC > DF, this must mean angle ABC is larger than angle DEF. This is because the longer a side is, the larger the opposite angle will be.
Therefore, this leads to angle ABC > angle DEF
--------------------------------------------------
This is what the steps will look like
angle ABC > angle DEF
angle DEF < ABC
0 < angle DEF < angle ABC

some students decide to take a bike ride. for the first two hours they travel at a speed of 15 mi/hr, they then stop for lunch for an hour. the students then ride for another hour at 10 mi/hr. what was their average speed for the trip?
10 miles per hour is the average journey speed.
Given that,
Some pupils choose to ride bikes. They move at a 15 mph average speed for the first two hours, and then they stop for lunch for an hour. The pupils ride at a 10 mph speed for an additional hour.
Average speed is ( total distance ) / ( total time )
During the 1st 2 hrs:
distance = speed * time
distance = 15 *2 = 30 miles
During the last hour:
distance = speed * time
distance = 10 *1 = 10 miles
Average speed = 30+10 / 2+1+1 = 40/4 = 10 mil/hr
Therefore, their average speed for the trip is 10 mil/hr

Likert scales are designed to be ordinal in measurement.
What is Likert scale and why is it used ?
The Likert scale is a psychometric scale that is used in survey questions that are based on it. It is one of the most popular sorts of survey questions. Respondents in a Likert scale survey are given precise options based on whether they "agree" or "disagree" with a particular survey question rather than just selecting "yes" or "no."
Likert scale survey questions are crucial for gauging a respondent's attitude or view toward a certain topic and are therefore a vital component of market research. Likert scales are commonly used to gauge respondents' levels of agreement with diverse claims using a five-, seven-, or nine-point scale. The Likert Scale was created by organizational psychologist Rensis Likert to evaluate the degree of agreement or disagreement on a symmetric agree-disagree scale. In general, a series of statements is used, each intended to look at a construct from a little different angle. The effectiveness of this method lies in the fact that it can be applied to both social science and marketing constructs.
Therefore, likert scales are designed to be ordinal in measurement.

A company that manufactures bicycles has a fixed cost of $90,000. It costs $200 to produce each bicycle. The total cost for the company is the sum of its fixed cost and variable costs Write the total cost, C, as a
function of the number of bicycles produced, x Then, find and interpret C(100)
The total cost function is C(x)=
Answer:
Total cost: C(x) = 90,000 + 200x in dollars
C(100) = $110,000
This means that the total cost for the company when it produces 100 bikes would be $110,000
Step-by-step explanation:
First, you have a fixed cost, so you would start by setting C(x) to that:
C(x) = 90,000
Then, you have a cost of $200 PER bike that is made. The amount of bikes is represented by x. So you will have to multiply cost per bike by how many bikes are manufactured:
200x
Add this variable cost to the function underlined above.
C(x) = 90,000 + 200x
This is your function C(x).
Now for C(100), PLUG IN 100 for x:
C(100) = 90,000 + 200(100)
Multiply out:
C(100) = 90,000 + 20000
Then add these together to get the value:
C(100) = 110,000
This is the amount of money it would cost to make 110000 bikes, as interpreted above.

cupcakes?
The number of jumbo cans of frosting would she need to frost 280 cupcakes is 8.
Given that, Bette used 3 jumbo cans of frosting to frost 105 cupcakes and 5 jumbo cans of frosting to frost an additional 175 cupcakes.
What are proportions?Proportion is a mathematical comparison between two numbers. According to proportion, if two sets of given numbers are increasing or decreasing in the same ratio, then the ratios are said to be directly proportional to each other.
Let number of jumbo cans of frosting would she need to frost 280 cupcakes be x.
Now the proportion is
3/105 = 5/175 = x/280
⇒ 5/175 = x/280
⇒ 175x = 280 × 5
⇒ x = 1400/175
⇒ x = 8

Answer:

You want the repeating decimal cost ...
[tex]\$3.\overline{23}[/tex]
written as a fraction and as a mixed number.
FractionOne can convert the repeating decimal to a fraction by multiplying it by a power of 10 equal to the number of repeating digits.
This cost number (C) has 2 repeating digits (23), so we want to multiply it by 10^2:
[tex]100C=10^2\times3.23\overline{23}=323.\overline{23}[/tex]
Now, we can subtract the original cost to cancel the repeating decimal fraction:
[tex]100C -C = 323.\overline{23}-3.\overline{23}=320[/tex]
Dividing by the coefficient of C, we have the fraction we want:
[tex]C=\boxed{\dfrac{320}{99}}[/tex]
Mixed numberThis is expressed as a mixed number by figuring the quotient and remainder.

Write the equation of the line perpendicular to y=5/6x+7/6 that passes through the point (-7,5)
The equation of the line perpendicular to y=5/6x+7/6 that passes through the point (-7,5) is y = (-6/5)x -17/5 .
In the question ,
it is given that the required line is perpendicular to y=5/6x+7/6 .
on comparing it with the slope intercept form of the line , we get
slope(m₁)= 5/6
So, the slope of the perpendicular(m₂) line will be
m₂= -1/m₁
m₂= -6/5
hence, slope(m₂) of the perpendicular line = -6/5
Given that the perpendicular line is passing through (-7,5)
substituting the values in slope intercept form (y=mx+c) of the line , we get
5 = (-6/5)(-7) + c
5 = 42/5 + c
c = 5-42/5
= (25-42)/5
= -17/5
y intercept = -17/5
so , the equation of the perpendicular line is y = (-6/5)x -17/5 .

a particular fruit's weights are normally distributed, with a mean of 717 grams and a standard deviation of 18 grams. if you pick 12 fruits at random, then 16% of the time, their mean weight will be greater than how many grams? give your answer to the nearest gram.
If the mean is 7171 grams, the standard deviation is 18 grams and 12 fruits are selected at random. Then, the mean weight will be 734.901 grams greater.
Let X be the random variable of the fruit's weight.
We have, the mean and standard deviation as 717 grams and 18 grams respectively.
We want to find the specific gram value for which 16% of the fruits are heavier, i.e. the 84th percentile of X's normal distribution
Now, Solving for x:
P( X < x ) = Normal( 717, 18 ), Z = 0.84
So,
P( [X - 717] / 18 < [x - 717] / 18 ) = P( Z < [x - 717]/18 ) = 0.84, where Z is a standard normal random variable
Now,
Standard Normal CDF( [x - 717]/18 ) = 0.84
Then, from the standard normal table: [x - 717]/18 = Inverse Standard Normal CDF( 0.84 ) = 0.9945
Therefore,
[ x - 717 ] / 18 = 0.9945
Multiplying 18 on each side of the equation,
x - 717 = 0.9945 × 18
x - 717 = 17.901
Adding 717 on each side of the equation,
x - 717 + 717 = 17.901 + 717
x = 734.901
