Miguel reads that the average low temperature today is −8.5°F and that the average high temperature is 10.2º F.
Miguel plots the points on the number line to determine the temperature change between these two readings.
What is the temperature change?
The change in temperature between the two readings as measured by Miguel is 18.7°F .
In the question ,
the temperature readings on the Miguel is
Average low temperature = -8.5°F
Average high temperature = 10.2°F
the change in the temperature , is given by the difference between the two reading .
which means
Change in temperature = Average high temperature - Average low temperature .
Substituting the values of average high and average low reading of the temperature from above ,
we get ,
Change in temperature = 10.2 -(-8.5)
= 10.2 + 8.5
= 18.7
the temperature change is 18.7°F .
Therefore , the temperature change is 18.7°F .

∠a=90° as the rays of the angles meet at the right angle that is 90°.One of the angle is 21, The remaining would be 90-21=69°.
What is an angle?When two straight lines or rays intersect at a common endpoint, an angle is formed. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
What is ray?A ray is a vector that extends from one point to another. A ray is typically defined in geometry as a half-infinite line (also known as a half-line) with one of the two points and taken to be at infinity.
What is right angle?The right angle is formed when two straight lines intersect at 90 degrees or are perpendicular to each other at the intersection. The symbol is used to represent a right angle.∠

If Gabriella has 3 more nickels than dimes and they have a combined value of 90 cents, how many of each coin does she have?
Correct dimes
nickels
If Gabriella has 3 more nickels than dimes and they have a combined value of 90 cents, The number of coin she have is; 4 nickels and 7 dimes.
Nickels and dimesx = number of nickels that Gabriella has
x +3 =number of dimes that Gabriella
Hence,
0.05x + 0.10 ( x + 3 ) = 0.9
Solving for x
Multiply both sides of the equation by 100 so as to eliminate two decimal places
5x + 10x + 30 = 90
Collect like terms
15x = 60
Divide both side by 15x
x = 60/15
x = 4 nickels
So,
x + 3 where x = 4
4 + 3 =7 dimes
Therefore she has 4 nickels and 7 dimes.

A cashier has 35 bills, all of which are $10 or $20 bills. The total value of the money is $520. How many of each type of bill does the cashier have?
After solving some mathematical operations we can conclude that the cashier has 16 bills of $10 and 18 bills of $20.
What do we mean by mathematical operations?A mathematical function called an operation, also known as an "operand" or "argument," transforms zero or more input values into a precisely defined output value.The quantity of operands affects the operation's arity.The operations that are most frequently studied are unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, and binary operations (i.e., operations of arity 2), such as addition and multiplication.An operation of arity zero also referred to as a nullary operation, is a constant.The mixed product is an illustration of an operation of arity 3, also referred to as a ternary operation.So, the total value of money by 35 bills is $0, and $20 is $520.
Now, we know that: 20 × 18 = 360Similarly, we know that: 10 × 16 = 160Sum of 360 and 160: 360 + 160 = $520So, 185 bills of $20 and 16 bills of $10.Therefore, after solving some mathematical operations we can conclude that the cashier has 16 bills of $10 and 18 bills of $20.

The quotient of 581 and 14 has a value of 40.07
How to evaluate the expression using partial quotients?The quotient expression is given as
581/14
Next, we express 581 as the sum of a multiple of 14 and another number
Say 581 = 280 + 280 + 1
So, we have the following equation
581/14 = (280 + 280 + 1)/14
Expand the bracket
So, we have the following equation
581/14 = 280/14 + 280/14 + 1/14
Evaluate the quotients
581/14 = 20 + 20 + 0.07
Evaluate the sum

Scores: 4, 8, 4, 4

-4
-12
-1
The value of the estimated standard error for the following set of D scores 4, 8, 4, 4 is 1.
The standard deviation of a statistic's sample distribution, or an approximation of that standard deviation, is the statistic's standard error. The term "standard error of the mean" is used when referring to a statistic that is the sample mean.
Consider the following set of D scores,
4, 8, 4, 4
We will calculate ∑D and ∑D² to find the SS for the D scores.
Therefore,
∑D = 4 + 8 + 4 + 4
∑D = 20
∑D² = 4² + 8² + 4² + 4²
∑D² = 16 + 64 + 16 + 16
∑D² = 112
Now, the formula for the standard score is given as:
[tex]SS=\sum D^2- \frac{(\sum)^2}{n}[/tex]
SS = 112 - [ (20)² /4 ]
SS = 112 - 100
SS = 12
Now,
[tex]S_{D}=\sqrt{\frac{SS}{n-1} }[/tex]
[tex]S_{D}=\sqrt{\frac{12}{4-1} }[/tex]
[tex]S_{D}=\sqrt{4}\\ S_{D}=2[/tex]
[tex]S_{\overline D}=\frac{S_{D}}{\sqrt{n} }[/tex]
[tex]S_{\overline D}=\frac{2}{\sqrt{4} }[/tex]
[tex]S_{\overline D}=\frac{2}{2}=1[/tex]
Hence, the standard error of the set of D scores is 1.

The baker can put all the 576 muffins in the box that contains exactly 9 muffins with none left over.
Can the baker put all the muffins in the box with none left over?In order to determine if the baker can put all the 576 muffins in the box that contains exactly 9 muffins with none left over, divide 576 by 9. If 9 perfectly divides 576, then there would be no remainder.
Division is the process in mathematics that is used to group a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations. Other operations in mathematics are addition, subtraction and multiplication.

What is the circle equation?r² = (x - h)² + (y - k)²is the standard equation for a circle, where (h,k) are the coordinates of the circle's center and r is the radius.
We must locate all points on the x-axis that are 12 units away from the starting point (3,-6).
Let these points be (x,0)
All points 12 units away from the point (3,-6) form a circle with a radius of 12 and a center at (3,-6). The formula would be as follows:
r² = (x - h)² + (y - k)²
12² = (x-3)² + (0+6)²
144 = (x-3)² + 36
(x-3)² = 108
