Step-by-step explanation:
Dana surveyed students in her class. She found that 8 earned an A, 6 earned a B, 4 earned a
C, and 2 earned a D on the last science test. If she randomly surveys one more student from
the class, what is the experimental probability that the student would have earned an A on
the test?

Answer:
2/5
Step-by-step explanation:
In order to find the probabability, you first need to find your total. So:
A, B, C, D,
8+ 6 + 4 + 2 =
20
Since, 20 is out toal it goes in our denominator
Now since we artrying to find the probability of A then we count the number of students who an A and place that in our denominator
8/20
We simplify
2/5

The school play is selling tickets for their annual fall play. Adult tickets cost $7 each and
children’s tickets cost $4 each. The theatre holds 100 seats and the play is sold out! If $592 were made off of ticket sales, how many of each kind of ticket were sold
Answer:
64 adult tickets were sold and 36 children tickets were sold
Step-by-step explanation:
i created two equations. 7A + 4C = 592 and A + C = 100. A stands for adult tickets and C stands for children tickets. in order to find the value of C, the children tickets, i took the second equation, A + C = 100, and subtracted A on both sides to get C = -A + 100. i then plugged the value of c into the first equation i created. i then got 7A + 4(-A+100) = 592. after that, i distributed the 4 into the parentheses and got 7A - 4A + 400 = 592. from there, you solve and get 3A = 192. divide 3 from both sides, and get the value of A = 64. then, you go back to the second equation, A + C = 100, and plug in your value of A to get 64 + C = 100. you can then go on to solve for C and get 36. your final answer is 64 adult tickets and 36 children tickets were sold.
Find the area of the figure above.
Answer:
84
Step-by-step explanation:
You do problems like these by finding the area of each shape individually and then adding them together. I first found the area of the rectangle by multiplying 6 in. by 11 in. to get 66 in.^2. I then found the area of the triangle by multiplying length of the base of the triangle which is the same as the short side of the rectangle at 6 in. by the 6 in. height and dividing it by 1/2. This gets 18 and 66+18=84
A major arc will have a measure that is
A. less than 180°
B. equal to 180°
C. greater than 180°
9514 1404 393
Answer:
C. greater than 180°
Step-by-step explanation:
Arcs are classified as "major" or "minor" depending on whether they are more or less than half a circle. A major arc is more than half a circle so is greater than 180°.
Solve for x: 10(x + 1) = 2x - 7
Answer:Simplifying
x = -2.125
Step-by-step explanation:Add '-10' to each side of the equation.
10 + -10 + 8x = -7 + -10
Combine like terms: 10 + -10 = 0
0 + 8x = -7 + -10
8x = -7 + -10
Combine like terms: -7 + -10 = -17
8x = -17
Divide each side by '8'.
x = -2.125
Simplifying
x = -2.125
i need help on this plz!
Its 23
Step-by-step explanation:
so the question is 5x - 7 = 28 What does x equal
Answer:
x=7
Step-by-step explanation:
Answer:
7
My Logic:
If you work backwards to simplify the eqation you can get x
take 5x-7=28 and add 7 to both sides. so now the eqaton looks like this: 5x=35. next you divide 5 into both sides and you will get 7!
Hope this helps!
According to the synthetic division below, which of the following statements
are true?
Check all that apply.
The correct statements about given synthetic division are C, D, and F
What is a quadratic polynomial?"It is a polynomial with degree 2."
What is synthetic division?"It is defined as a way of dividing one polynomial by another polynomial of first degree."
For given question,
We have been given a quadratic polynomial [tex]F(x)=4x^{2} -17x-15[/tex]
We can factorize above quadratic polynomial as,
[tex]F(x)\\=4x^{2} -17x-15\\=4x^{2} -20x+3x-15\\=4x(x-5)+3(x-5)\\=(x-5)(4x+3)[/tex]
This means the factors of [tex]4x^{2} -17x-15[/tex] are (x - 5) (4x + 3)
And the roots of the polynomial would be,
[tex]\Rightarrow F(x)=0\\\Rightarrow 4x^{2} -17x-15=0\\\Rightarrow (x-5)(4x+3)=0\\\Rightarrow x-5=0~~,~~4x+3=0\\\Rightarrow x=5~~,~~x=-\frac{3}{4}[/tex]
This means, the roots of [tex]4x^{2} -17x-15[/tex] are 5 and [tex]\frac{-3}{4}[/tex]
Therefore, the correct statements about given synthetic division are C, D, and F

Answer:
The 3 one
Step-by-step explanation:
So first you need to find all the angles.
Triangles all have a total degree of 180.
Then you can start doing trig. To find c I did (4sqrt3)cos60 that equals 3.464 which is 2sqrt3. Then I figured out a by doing the same thing but with sine. (4sqrt3)sin60 and that equals 6. Then I moved to the other triangle. I figured out d next. 6tan45° and that equals 6. Then I did b by doing 6/cos45 and I got 6sqrt2

Callum and Isobel have a total of 240 stamps.
The ratio of the number of Callum’s stamps to the number of Isabel’s stamps is 3:8.
Callum buys some stamps from Isabel.
The ratio of the number of Caullum’s stamps to the number of Isabel’s stamps is now 3:2
How many stamps does Callum buy from Isabel?
You must show all your working.
Please help.
Answer:
Total stamps = 240
ratio= 3:8
3x + 8x = 240
11x = 240
x = 240/11 = 21.8
then, callum's stamps = 3x = 3 * 21.8 = 65.4
Isabel's stamps = 8x = 8 * 21.8 = 174.4
After buying the stamps,
ratio = 3:2
callum's stamps = 3x
Isabel's stamps = 2x
= 3x + 2x = 240
5 x = 240
x = 240/5 = 48
callum's stamps = 3x = 3 * 48 = 144
Isabel's stamps = 2x = 2 * 48 = 96
no. if stamps bought by calling = 144 - 65.4 = 78.6 stamps
