Answer:

66 degrees! Hope it Helps!!!!

Step-by-step explanation:

So the total angle amount of a square is 360

lets first figure out what x is...

angle B and angle D is equal, forming a equation.

6x-96=3x

simplify that...

x=32

Now pluggin x into the equation (6x-96)&(3x)

96 and 96

Now add all the angles forming this equation: (?+102+96+96=360)

The slope formula can be used to find the slope, m, of a line with points (L1, y1) and (22, 42).
Helga [31]

Answer: (y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)

Step-by-step explanation:

Point slope form: (y-b)=n(x-a) , where n=slope , (a,b) is the point through which line passes.

If slope of the line = m and line passes through (x_1,y_1) and (x_2,y_2) :-

(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)

So, the equivalent equations are :

(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)

Question Help When purchasing bulk orders of batteries, a toy manufacturer uses this acceptance sampling plan: Randomly select a
S_A_V [24]

Answer:

Step-by-step explanation:

Here X no of defective batteries is binomial with p = 1% = 0.01

q = 1-p=0.99

(Because each battery is independent and there are only two outcomes)

Prob that shipment is accepted is for n =36, P(X\leq 2)

=P(x=0,1,2)

= \Sigma^2_0  36Cr (0.01)^r (0.99)^{36-r}

= 0.9944

A number, n, is added to 15 less than 3 times itself. The result is 101. Which equation can be used to find the value of n? 3n –
yawa3891 [41]

Answer:

A : 3n - 15 + n = 101

Step-by-step explanation:

Solution:-

- We will denote a number as "n".

- The result of 3 times itself less 15 would be:

                         3*itself - 15

                         itself = n

                         3*n - 15

- Then a number "n" is added to the above result:

                         3*n - 15 + n.

- The result of above expression is 101:

                         3*n - 15 + n = 101

- Option A is the correct answer
