Given:
The scale on a map is 1:25000.
To find:
How many km on the ground is represented by 6cm on the map?
Solution:
Let x be the km on the ground.
We know that,
1 km = 1000 m
1 m = 100 cm
So,
1 km = 100,000 cm
x km = 100,000x cm
The scale on a map is 1:25000. It means the ratio of map and ground is equal to 1:25000.
[tex]\dfrac{1}{25000}=\dfrac{6}{100,000x}[/tex]
[tex]\dfrac{100,000x}{25000}=6[/tex]
[tex]4x=6[/tex]
[tex]x=\dfrac{6}{4}[/tex]
[tex]x=1.5[/tex]
Therefore, 1.5 km on the ground is represented by 6cm on the map.
Instead I’d using the values 1,2,3,4,5,6 on dice, suppose a pair of dice have the following 1,2,2,3,3,4 on one die and 1,3,4,5,6.8 on the other.find the probability of rolling a sum of 12
Answer:1/24
Step-by-step explanation:
Since the first die has 4 distinct numbers, and second has 6 distinct numbers, so total number of combinations possible = 4 × 6 = 24
Now, the number of chances where we get the rolling sum as 12 is only one. (
Therefore, the probability of getting sum 12 is 1/24

Please help ??
Answer:
n < 2
Step-by-step explanation:
Answer: Look at the explanation please.
Step-by-step explanation:
The first thing you would do is distribute the 2 to the n and the 3.
You will then get 2n+6-4<6
Next, you will have to subtract 6-4 and you will get 2
You will the have 2n+2<6
Subtract 2 from 2 to get 0 and from 6 to get 4.
Your left with 2n<4
Then, divide 2 from 2n and 2 from 4
Last, your answer will be n<2.
Graphing
Your graph would look like (from what I see in my book)
You have seven tick marks and in the middle will be 0.
From the left of 0 should have negative 1, 2, and 3
From the right of 0 would be positive 1, 2, and 3
On the top of 2 would be a open circle and an arrow going to the left.
Hope this helps :)

The measures of the angles of a triangle are shown in the figure below. Solve for x.
Answer: 27°
Step-by-step explanation: Here, we're asked to find the missing angle measure in the triangle shown which is represented by the variable x.
To find the value of x, remember that the sum of the
measures of the angles in a triangle is 180°
So we can setup the equation 63 + 90 + x = 180.
Remember that a box indicates a 90° angle.
Now to solve for x, let's first simplify on the left side of the equation.
63 + 90 is 153 so we have 153 + x = 180.
Now to get x by itself, we subtract 153 from both sides of the equation.
On the left side of the equation, 153 - 153 cancels out and we have x
and on the right side of the equation, 180 - 153 is 27.
This means that the missing angle in the triangle is 27°.

Using the compound interest formula, the "n" is what value when compounded annually?
Answer:
n=1
Step-by-step explanation:
N is the number of times per year
Annually would be one time per year so n =1
Answer:
If interest is compounded yearly, then n = 1; if semi-annually, then n = 2; quarterly, then n = 4; monthly, then n = 12; weekly, then n = 52; daily, then n = 365; and so forth, regardless of the number of years involved. Also, "t" must be expressed in years, because interest rates are expressed that way.

One year ago, Lindsey deposited $250 into a savings
account. Her balance
deposited $250 into
now $253, Two years ago, Jenn
savings account Her balance is
now $257.50. Which account has the greater simple
interest rate? Explain,
Answer:
Jenns account has the greater simple interest rate.
Step-by-step explanation:
The formula for simple interest is:
A = P * ( 1 + r * t )
Where A is the final amount after investment, P is the initial amount, r is the rate of interest and t is the time periods.
For Lindsey:
253 = 250 * ( 1 + r * t )
Solve for r
r = ( 253/250 ) - 1 = 0.012
Lindsey simple interest was 1.2% annually
For Jenn:
257.50 = 250 * ( 1 + r * 2 )
r = ( 257.50/250 ) - 1 )/2 = 0.015
Jenn simple interest was 1.5% annually
Therefore Jenns account has the highest simple interest rate.
Answer:
Lindsay’s interest is $3 for one year. Using the formula for interest, I = prt, Lindsey’s money is earning at a rate of 1.2%. Jenn has earned $3.75 for one year. Her money is earning at a rate of 1.5%, which is a higher interest rate.

What single decimal multiplier would you use to increase by 10% followed by a 16% decrease?
The single decimal multiplier is 0.924.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
To find the single decimal multiplier:
First, increase by 10%.
100 + 10% = 110%
And number multiplier is 1.10.
Then, a followed by a 16% decrease.
That means,
100-16 = 84%
So, number multiplier is,
(1.10)(0.84) = 0.924
Therefore, the single decimal multiplier is 0.924.

5,000 grams is equal to 5,000/1000 = 5 kilograms. The correct option is C
What is kilograms ?A unit of measurement used to describe mass or weight is the kilogram (kg). It is widely used all over the world to measure an object's weight because it is the International System of Units' (SI) fundamental unit of mass.
To convert grams to kilograms, you divide the number of grams by 1000 since there are 1000 grams in one kilogram.
So, 5,000 grams is equal to 5,000/1000 = 5 kilograms.
Therefore, the correct option is C. 5 kilograms.

A bank's loan officer rates applicants for credit. the ratings are normally distributed with a mean of 200 and a standard deviation of 50. if an applicant is randomly selected, find the probability of a rating that is between 200 and 275.
Answer:
0.4332 = 43.32% probability of a rating that is between 200 and 275.
Step-by-step explanation:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
A bank's loan officer rates applicants for credit. the ratings are normally distributed with a mean of 200 and a standard deviation of 50
This means that [tex]\mu = 200, \sigma = 50[/tex].
Find the probability of a rating that is between 200 and 275.
This is the pvalue of Z when X = 275 subtracted by the pvalue of Z when X = 200. So
X = 275
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{275 - 200}{50}[/tex]
[tex]Z = 1.5[/tex]
[tex]Z = 1.5[/tex] has a pvalue of 0.9332
X = 200
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{200 - 200}{50}[/tex]
[tex]Z = 0[/tex]
[tex]Z = 0[/tex] has a pvalue of 0.5
0.9332 - 0.5 = 0.4332
0.4332 = 43.32% probability of a rating that is between 200 and 275.
