Answer:
-10.49.
Step-by-step explanation:
Using order of operations PEMDAS:
4(-8+4.5)/ 6.25 + (-8.25)
= 4 * -3.5 / 6.25 - 8.25
= -14/6.25 - 8.25
= -2.24 - 8.25
= -10.49.
Answer:
The probability that the animal chosen is brown-haired is 0.6333.
Step-by-step explanation:
Denote the events as follows:
<em>A</em> : a brown-haired rodent
<em>B</em> : Litter 1
The information provided is:
The probability of selecting any of the two litters is equal, i.e.
According to the law of total probability:
Compute the total probability of event <em>A</em> as follows:
Thus, the probability that the animal chosen is brown-haired is 0.6333.
Answer:
d)0 and 7 are solutions of the original equation.
Step-by-step explanation:
Let's solve your equation step-by-step.
w=√7w
Step 1: Flip the equation.
√7w=w
Step 2: Solve Square Root.
√7w=w
7w=w2(Square both sides)
7w=w2
7w−w2=w2−w2(Subtract w^2 from both sides)
−w2+7w=0
w(−w+7)=0(Factor left side of equation)
w=0 or −w+7=0(Set factors equal to 0)
w=0 or w=7
Check answers. (Plug them in to make sure they work.)
w=0(Works in original equation)
w=7(Works in original equation)
Answer:
<em>The equation will be: </em>
Step-by-step explanation:
The number of student tickets that were sold
and the number of other tickets that were sold
Student tickets cost $3 a piece and tickets for everyone else cost $5 each.
So, <u>the total cost of</u> <u>student tickets</u> and <u>the total cost of</u> <u>other tickets</u>
Given that, the drama club sold <u>total $779 worth of tickets</u>.
So, the equation will be:
