Answer: B.

Step-by-step explanation: The probability that a student is 15 years old includes those who are only 15: 450 students. This means that of 1,500 there are 450 students who are 15. The probability is set up as: 450/1,500 or 0.30.

Which statement is not a solution of the inequality 5-2x>-3?
mart [117]

Answer: D

Step-by-step explanation:

D states that x is 5. If x were 5, the number on the left side of the inequality would be -5. The left side of the inequality must be equal to or greater than -3. -5 is less than -3, so it does not fit.

TV Cabinet TV screens are measured on the diagonal. If we have a TV-cabinet that is 72 inches long and 64 inches high, how large
lesya692 [45]

Answer:

<h2> 94in</h2>

Step-by-step explanation:

We are expected to solve for the diagonal of a rectangular shape.

given that the length, l=72in

width, w=64in

we can apply the Pythagoras theorem to solve for the diagonal since it corresponds to the hypotenuse of the rectangle

note: we are to leave 2-inches on all sides for the edging of the TV

l=72-2= 70 in

w=64-2=62

diag=√l^2+w^2

diag=√70^2+62^2

diag=√4900+3844

diag=√8744

diag=93.50 in

to the nearest tenth, it is 94in

Quadrilateral OPQR is inscribed in a circle as shown below...
kipiarov [429]
We can use the fact that a cyclic quadrilateral (i.e. a quadrilateral inscribed in a circle) has the opposite angles supplementary, therefore
2x+(2x+4) = 180
Solving for x:
4x+4=180 
4x=180-4=176
x=176/4=44 &deg;
=>
angle O = 2x = 88 &deg;  
angle Q=180-O=180-88 = 92 &deg;

Similarly,
(3y+8)+y= 180
=> y=43 &deg;
=>
P=y=43 &deg;
R=180-43=137 &deg;
