Answer:
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.
There are 6 options on the dessert menu at a restaurant. Akira and Paula like all of the choices equally, so they each choose a dessert at random from the menu. What is the probability that Akira will choose apple pie and Paula will choose strawberry cheesecake for dessert? Express your answer as a decimal. If necessary, round your answer to the nearest thousandth.

The probability that Akira will choose apple pie and Paula will choose strawberry cheesecake for dessert is; B: 0.028
What is the probability of selection?
We are told that;
There are 6 dessert options menu.
Now, Akira and Paula like all of the choices equally. Thus, probability of selecting any of the 6 menus will be; P(select 1 menu) = 1/6
Thus, probability that they select the preferred menu written in the question is; P(both select 1 menu) = 1/6 * 1/6 = 0.028

There are 4 times as many dogs as cats if the total number of dogs and cats is 25 how many dogs are there
Answer:
6 times as many dogs as cats
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
So we know that if we combine all of the dogs and cats, we get 25. We also know that there are 4 times more dogs than cats, so we can call cats x, and dogs 4x.
So 4x + x = 25
5x = 25
x=5
There are 5 cats. Now that we know the number of cats , we just need to multiply that by 4, which is 20 dogs.
Here is a list of ingredients: 260g of butter, 500g of sugar, 650g of flour, 425g of rice to make 20 biscuits. Michael has 2kg of each ingredient. Work out the greatest number of biscuits that he can make.
Answer: 61 Biscuits
Step-by-step explanation: 13g of butter per biscuit, 25g sugar per biscuit, 32.5g flour per biscuit, 21.25g rice per biscuit
By taking the amount of flour per biscuit (the largest ingredient) and dividing 2000 by it you get 61 which is the most amount of biscuits he can make with his ingredients.

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.
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
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.

Step-by-step explanation:
At a particular school 20% of children travel by bus.
If this represents 280 children, how many children attend the school?
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 ✓
Which value for x makes the equation x -4.21 = 6.047 true? A. x = 10.68 C. X = 10.247 B. x = 10.257 D. x = 1.837
Answer:
C. X = 10.247
Step-by-step explanation:
X -4.21 = 6.047
just you will add 4.21 to both sides of the equation
X -4.21 + 4.21 = 6.047 + 4.21
X = 10.247

Answer:
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.
Which equation, when graphed, has x-intercepts at (−1, 0) and (−5, 0) and a y-intercept at (0, −30)? f(x) = −6(x 1)(x 5) f(x) = −6(x − 1)(x − 5) f(x) = −5(x 1)(x 5) f(x) = −5(x − 1)(x − 5).
Answer:
f(x) = −6(x+ 1)(x +5)
Step-by-step explanation:
x-intercepts at (−1, 0) and (−5, 0)
so the roots are -1 and -5 (where the graph intersects the x-axis)
this will give us that f(x) = (x- root1)(x-root2) = (x- -1)(x- -5) = (x+1)(x+5)
y-intercept at (0, −30) is telling us that when x= 0 the y = -30
y = a ( x+1)(x+5) , in general
y = a(0+1)(0+5), is the equation if x=0
-30 = a·1·5, we need y= -30 when x= 0
-30 = 5a , divide both sides of the equation by 5
-6 = a
The correct choice is :
f(x) = −6(x+ 1)(x +5)
f(x) = −6(x − 1)(x − 5)
f(x) = −5(x +1)(x +5)
f(x) = −5(x − 1)(x − 5).
