104 degrees
Step-by-step explanation:
RS is a line, so it is 180 degrees. PO is also a line and point O is touching line RS. The acute measure is 76 degrees, as shown. To find the other angle measure for SOP, subtract 76 from 180. That gives 104 degrees, which is the measure of SOP.

An outlier point is added to a set of bivariate data. In what way must your analysis change with the addition of the outlier?
A. The sign of the regression coefficient will change from positive to
negative, or vice versa.
B. The value of the correlation coefficient will move closer to 0.
C. The regression constant will change dramatically.
D. All of the above.
Answers
Answer:
I already said b in the comment area so I'm just putting it here now
Step-by-step explanation:
(B) The value of the correlation coefficient will move closer to 0.
Bivariate data:Bivariate data in statistics refers to data on two variables, each of which has a value coupled with a value of the other variable. Normally, it would be interesting to look into any potential relationships between the two variables. The association can be investigated using sample statistics that can be utilized for inference, a tabular or graphical display, or both. The approach taken to look into the association would depend on how the variable was measured. Bivariate correlation or bivariate association are terms used to describe the links, which only involve two variables.Therefore, the correct option is (B) The value of the correlation coefficient will move closer to 0.

What is The difference of 3 and a number X
Answers
Answer:
"the difference of" means to subtract
Therefore, "the difference of 3 and a number" would be:
3-x
Step-by-step explanation:
The required number is 63 and its 20% will be 12.6.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.
The difference between 3 and the number x of that number is -60.
According to the question, the algebraic form will be as:
⇒ 3 - x = -60
⇒ x = 60 + 3
Apply the addition operation,
⇒ x = 63
So the required number is 63
20% of the number = (20/100) × 63
20% of the number = (0.20) × 63
20% of the number is 12.6.
Therefore, the required number is 63 and its 20% will be 12.6.

At a particular school 20% of children travel by bus.
If this represents 280 children, how many children attend the school?
Answers
Answer:
1,400 children attend the school
Step-by-step explanation:
If 20% is 280, we can set up a proportion to solve for how many attend the school. I will put the percentages on top and the number of children on the bottom:
-> Please note that a percentage divided by 100 becomes a decimial
[tex]\frac{20}{280}=\frac{100}{x}[/tex]
Cross multiply:
.2 * x = 280 * 1
.2x = 280
Divide both sides of the equation by .2:
1,400 children attend the school
We can check our work by multiplying 1,400 by 0.2:
1,400 * 0.2 = 280 ✓

Triangle STU is not similar to Triangle VWU
Step-by-step explanation:
For two triangles to be similar, they both should have the same angle measures. To find out if they have the same angle measures, we have to solve for the unknown angles. Remember, a triangle is worth 180°.
Triangle STU:
x + 90 + 42 = 180x + 132 = 180x = 48Triangle VWU:
x + 58 + 90 = 180x + 148 = 180x = 32As you can see, the angles don't have the same angle measures. Thus, they are not similar.

During his leg of the run, Shannon developed hypothermia, a dangerous condition caused by extreme cold. Normal body temperature is 98.5ºF. During hypothermia, it falls by at least 3.5º. If his temperature dropped by that amount, what was Shannon’s body temperature with hypothermia?
Answers
= 98.5 °F
Temperature falls by 3.5 °F during hypothermia
Hence there is a decrease in the normal temperature
Therefore the temperature during hypothermia
