Answer: C , 0.29
Step-by-step explanation:
P(D) is the probability flirting of directly in person.
represents probability of flirting other than in person.
P(D)=0.710.
= 1 - 0.710.
= 0.29
Hence the value of Upper P left parenthesis Upper D overbar right parenthesis is 0.29.

14 is the GCF of a number M and 210. What are possible values of M?
Answer:
Hello,
we know that to find the GCF we descompose the numbers and then we multiply the common terms with the lowest exponent. So we first descompose 210:
210 | 2
105 | 3
35 | 5
7 | 7
1
210= 2x3x5x7
Now one possible solution is 14 because:
14 | 2
7 | 7
1
As you can see 2 and 7 are common terms, so:
GCF= 2x7
GCF=14 --> It's correct
Then, if we analyze it, we'll realize that we have an infinitive number of solutions. The only requirement is that "M" must have 2 and 7 when we descompose it.
For example:
M= 2²x7x3x11
M=924
924 is another possible solution, it doesn't matter if 2 or 7 repeat, since I said the GCF is the multiplication of the common terms with the LOWEST exponent. That's all.

what is 78+34 is the same as 80+
Answer:
112 its the same as 80 + 32
The expression is 78+34=80+32
What is equivalence?Equivalent equations are algebraic equations that have identical solutions or roots. Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation.
Given here, 78+34=112 and 80+32 =112 thus, 78+34=80+32 The equivalence is preserved.
Hence, The expression is 78+34=80+32

Answer:
11. <

Four friends made 55 cupcakes and shared them equally.
How many cupcakes did each friend get?
Out of the 55 cupcakes shared equally among four friends each friend will have 13 cupcakes.
What is the unitary method?A unitary method is a mathematical technique for finding the value of a single unit and then deriving the required units by multiplying with the single unit.
To find how many cupcakes each friend gets we can use the unitary method.
Given four friends made 55 cupcakes, therefore each friend can have (55/4) = 13.75 cupcakes, But the no. of cupcakes should be integers.
∴ Each friend can have 13 cupcakes.

Write the ratio as a unit rate. Simplify. 216 diving student and 12 instructor
Answer:
Ratio students to classroom in school A equals 216:12 which simplifies to 18:1. Ratio students to classroom in school B equals 104:4 which simplifies to 26:1.Total students combining school A and B equals 216+104=320 and Total classroom 12+4=16, if both school combined are assumed to be a single school C, than ratio of of students to the classroom in school C equals 320:16 which simplifies to 20:1 which means 20 students in every classroom, now total students in 4 classroom of School C equals 20x4=80, these 4 classroom are separated as School B and other 12 classroom School A, now ratio still 20:1 (same in both schools). initially students in School B were 104 and now are 80, then total students transferred equals 104-80= 24.

Answer:
The answer to your question is given below.
Step-by-step explanation:
To know the correct answer to the question, do the following:
√12 + √108
= 12^½ + 108^½
= 4^½ • 3^½ + 36^½ • 3^½
Factorise
3^½ (4^½ + 36^½)
Recall:
4^½ = √4 = 2
36^½ = √36 = 6
Therefore,
3^½ (4^½ + 36^½) = 3^½ (2 + 6)
= 3^½ • 8

Her original recipe calls for 1/3 cups of cocoa powder and 1/2 cups of flour. I saw we just added 2 more units to the cocoa powder! So, I decided that we should also add 2 more units to the flour and that is how I got 1 1/2 cups of flour.

Write the equation of the line graphed below.
Answer:
In y intercept form, the equation would be: Y= -1/3x -6
Step-by-step explanation:
In order to find the equation, you can use any points given. In this case, I used (-6,-4) and (-3,-5).
With these points, you must find the slope. The change in our y values is -1 and the change in our x values is +3.
Now we have Y= -1/3x
To find the y intercept, you look on the graph for where there's a point that is lying on y line. In this case (0,-6) is lying on the y line. This means that the Y intercept for our equation is -6. Another example is (0,8), our y intercept would be 8 because the x value is 0!
In conclusion, our equation in y intercept form would be Y= -1/3x-6
Hope this helps!! :)
