Answer:
367
Step-by-step explanation:
because of PEMDAS, 3, 4, 5, and 6 have to be multiplied together, then 7 can be added later.

Answer:
d
Step-by-step explanation:
We know that diagonals bisect angles of a rhombus, meaning that they split the angles of two equal parts, that opposite angles are equal, and that the angles of a quadrilateral, such as a rhombus, add up to 360 degrees.
Looking at the drawing I uploaded, and taking into account that diagonals bisect angles of a rhombus, we can say that angle x = y and z = 5x-18
Next, given that opposite angles are equal, we can say that angle B = angle D and angle A = angle C. Therefore,
A+B+C+D= 360 (as the angles of a quadrilateral add up to 360)
A + B + A + B = 360 (plugging in A for C and B for D)
2 ( A + B) = 360
A + B = 180
x + y + z + 5x - 18 = 180 (plugging x+y in for A, and z+5x-18 in for B, as x and y make up A and z and 5x-18 make up B)
x+x+5x-18+5x-18 = 180 (because x=y and z=5x-18)
2(x+5x-18) = 180
divide both sides by 2
x+5x-18=90
6x-18=90
add 18 to both sides
6x=108
divide both sides by 6
x = 18
Answer:
4. A survey asking 75 people if they like the new school building
Step-by-step explanation:
A binomial experiment consist of n trials but for every trial there are only two possible outcomes.
1. A survey asking 75 people to name their favorite color
There can be more than two answers to the given question so it is not a binomial experiment.
2. A survey asking 75 people to give their age
The age can be any integer which makes the outcomes more than two so this is also not a binomial experiment.
3. A survey asking 75 people whom they voted for in the election
This is also not a binomial experiment as there can be more than two answers to the question
4. A survey asking 75 people if they like the new school building
The given question can only be answered in yes or no which means only two possible outcomes so this is a binomial experiment ..
Answer: The answer is b 2nd one
Step-by-step explanation:
Explanation - 2a + 2a = 4a + a + a = 6a and 4 + 4 = 8 so 6a + 8
