Answer:
D
Step-by-step explanation:
Its 5x (on bottom row, its the simplest way to put it), and 625 x 5 = 3125, then 3215 x 5 = 15625. So its D.
Answer:
D
Step-by-step explanation:
If you look closely, you may see a pattern in the denominators.
the 1st one is 5,
the 2nd one is 5²
the 3rd one is 5³
so it is only reasonable that the next 2 are 5^4 and 5^5

A thief gave me 3 eggs
My farm rooster lays 5 eggs
How many eggs do I have?
Using basic operations, it is found that you have 12 eggs.
----------------------------------
Initially, you had 4 eggs.When the thief gave you 3 eggs, these 3 eggs were added to your amount, thus, you had 4 + 3 = 7 eggs.When the farm rooster laid 5 eggs, these 5 eggs were added to your amount, thus, at the end, you ended up having 7 + 5 = 12 eggs.A similar problem is given at https://brainly.com/question/24459209

At a sale, dresses were sold for $34 each. This price was 85% of a dress's original
price. How much did a dress originally cost?
Answer:
The original price was $40
Step-by-step explanation:
let x = original price
34= 0.85x
Divide both sides by 0.85
34/0.85 = x
40 = x
Check:
0.15 × 40 = 6
40 – 6 = 34
Data will be collected on the following variables. Which variable can be considered discrete? A. The height of a person B . The weight of a person C. The length of a person’s arm span D The time it takes for a person to solve a puzzle E The number of books a person finished reading last month
Answer: E: The number of books a person finished reading last month
Step-by-step explanation:
First, a discrete variable is a variable that only can take some given values in a set, the discrete variables are usually not dense, and a continuous variable is a variable that can take any value in a range (where the accepted values are dense).
So, for example, the set of the natural numbers is discrete, and the set of the real numbers can represent a continuous variable.
Here the only option that is really discrete will be the number of books that a person finished reading last month because here only positive whole numbers are accepted (you can not finish a 0.454 of a book)
The other options are continuous because all are classical measures.
For example, the weight of a person can jump between:
75.6kg and 75.7kg.
So you could think that this is discrete because the values between 75.6kg and 75.7g are not shown with our measuring device, but those will be added in the error of the measure because the weights between 75.6kg and 75.7kg are actually possible, so they must be accepted.
Option E is right.
A. The height of a person. Height is a continuous variable.
B . The weight of a person. Weight is a continuous variable.
C. The length of a person’s arm span. Length is a continuous variable.
D. The time it takes for a person to solve a puzzle. Time is a continuous variable.
E. The number of books a person finished reading last month. The number of books is discrete variable.

6. Mary and Steve each travel 845 miles. Mary drove an average of 5 mph faster than Steve and completed the trip in one hour's less time
than Steve. What was each person's average speed?
Answer:
Steve had an average speed of 62.55 mph while Mary had an average speed of 67.55 mph
Step-by-step explanation:
Here, we want to calculate the average speed of each of the two.
From the question, we are told that Mary drove an average of 5 mph faster than steve.
So, let the average speed of Steve be x mph, this means that the average speed of Mary will be (x + 5) mph
Mathematically;
Time = distance/speed
Time taken by Steve = 845/x hours
Time taken by Mary = 845/(x + 5)
But Mary took an hour less to complete her own trip;
This means that;
if we add one hour to the time spent by Mary, then we will have the time spent by Steve
845/(x + 5) + 1 = 845/x
845/(x + 5) = 845/x -1
845/(x + 5) = (845 - x)/x
Cross multiply;
845(x) = (x + 5)(845-x)
845x = x(845-x) + 5(845-x)
845x = 845x-x^2 + 4225 - 5x
x^2 + 5x - 4225 = 0
We can solve this using the quadratic formula;
x = -b ± √(b^2 - 4ac)/2a
where a = 1 , b = 5 , c = -4225
x = -5 ± √(5^2 - 4(1)(-4225)/2(1)
x = -5 ± √(25 + 16,900)/2
x = -5 ± √(16,925)/2
x = (-5 + 130.1)/2 or (-5-130.1)/2
We ignore the negative side as speed cannot be negative
x = (-5 + 130.1)/2 = 62.548 which is approximately 62.55 mph
So steve’s speed is 62.55 mph while Mary’s speed = 62.55 + 5 = 67.55 mph

The variance of any standard normal distribution is________.
a) 0.5.b) -0.5.c) 0.d) 1.
Answer:
d) 1
Step-by-step explanation:
The variance of standard normal distribution is simply put as 1.
If you take it a bit further, even though not asked, the mean of a standard normal distribution is 0.
Therefore, the conclusion is that, the variance of a standard normal distribution is 1, while the mean of the same standard normal distribution is 0

Solve the following equation for a. 5b + 6a – 7 = 2b + 9a
Answer:
[tex]a=\dfrac{3b-7}{3}[/tex]
Step-by-step explanation:
Given that,
The given equation is :
5b + 6a – 7 = 2b + 9a
We need to solve the above equation for a. Taking he terms having a and b in LHS and constants in RHS.
5b+6a-2b-9a=7
taking like terms together
(6a-9a)+(5b-2b)=7
-3a+3b=7
Subtracting both sides by 3b. So,
-3a+3b-3b=7-3b
-3a=7-3b
Dioviding both sides by (-3). So,
[tex]a=\dfrac{7-3b}{-3}\\\\a=\dfrac{3b-7}{3}[/tex]
Hence, the value of a is [tex]a=\dfrac{3b-7}{3}[/tex].
Answer:
[tex]a = \frac{3b-7}{3}[/tex]

Step-by-step explanation:
Write the equation of a line that is parallel to 4x-2y=3 and is passing through the point (2,1)
Answer:
y= 2x -3
Step-by-step explanation:
Let's rewrite the given equation into the form of y=mx+c, so that we can find the gradient of the line. In this form, m (coefficient of x) is the gradient.
4x -2y= 3
2y= 4x -3
Divide by 2 throughout:
[tex]y = 2x - 1 \frac{1}{2} [/tex]
Thus the gradient is 2.
Parallel lines have the same gradient thus the line would also have a gradient of 2.
Substitute m=2 into the equation:
y= 2x +c
To find the value of c, substitute a pair of coordinates.
When x=2, y=1,
1= 2(2) +c
1= 4 +c
c= 1 -4
c= -3
Thus, the equation of the line is y= 2x -3.
