Find the range 4.7 6.3 5.4 3.2 4.9
Answers
Answer:
3.1.
Step-by-step explanation:
We have been given a data set and we are asked to find the range of our given data set.
4.7, 6.3, 5.4, 3.2, 4.9
First of all let us arrange our data set in ascending order.
3.2, 4.7, 4.9, 5.4, 6.3
Since we know that range is the difference between the greatest value and lowest value of the data set.
We can see that 6.3 is the greatest data point and 3.2 is the lowest data point of our given data set.
Upon substituting these values in range formula we will get,
Therefore, the range of our given data set is 3.1.
Range= Biggest number-Smallest Number
6.3-3.2=3.1
Thus, your answer.

c. There is no correlation between arithmetic skills and losing baby teeth.
d. There is a correlation here, and losing baby teeth causes arithmetic skills to improve.
Answers
Answer:
B. There is correlation but no direct casual relation, but losing teeth and arithmetic skills.
Step-by-step explanation:
Given:
Correlation between lost of baby teeth and arithmetic skills.
Solution:
Correlation and causality concepts are so used here.
Correlation is the relationship between two variables to get or to predict information.
Correlation is not always causation.
So here the correlation is used to predict the arithmetic skills based on lost teeth.
i.e. More teeth lost more arithmetic skills.
Causality means change in one variable changes value of other variable.
So it gives direct causal relation between the variables.
Here they given relationship between the children lost teeth and arithmetic skills to predict information.
But ,there no actual imply on correlation.
Arithmetic skills can also depends upon third variable.
Hence there is no direct causal relationship between them.

C is correct
Step-by-step explanation:
Given: (1,-6) rotate 270° counterclockwise rotation about the origin.
For 270° counterclockwise rotation about the origin.
(1,-6) lie in IV quadrant.
After 270° counterclockwise rotation about the origin
Point image form in III quadrant.
Hence, The image of (1,-6) is (-6,-1)

For this case we must find the solution of the following inequality:
5(x+5)<85
We apply distributive property on the left side of inequality:
5x+25<85
We subtract 25 from both sides of the inequality:
5x<85-25
5x<60
We divide between 5 on both sides of the inequality:
x<60/5
x<12
Thus, the solution is given by all values of x less than 12.
x<12
What is the equation?
An equation is a mathematical statement that is made up of two expressions connected by an equal sign. For example, 3x – 5 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 7.
What is the equation form?
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

Answer: $8.97
Step-by-step explanation:
he bought three jars and lowered the price by 75 cents for each, so multiply $0.75 by three
$0.75 * 3 = $2.25
so henri saved $2.25 in total
we can add that to what he paid to find the original cost
$6.72 + $2.25 = $8.97
so the original price was $8.97 :)
