If a → b is true, then ~a → b is also true.

Answer:

False

Step-by-step explanation:

To determine whether the statemaent "If a\Rightarrow b is true, then \neg a\Rightarrow b is also true" holds, you can form the truth table:

\begin{array}{ccccc}a&b&a\Rightarrow b&\neg a&\neg a\Rightarrow b\\1&1&1&0&1\\1&0&0&0&1\\0&1&1&1&1\\0&0&1&1&0\end{array}

When the result of the column a\Rightarrow b takes value 1 (true), the result of the column  \neg a\Rightarrow b is not always 1, then the statement is false.

Answer:

The equation simplifies to n = 7.

Step-by-step explanation:

Hey there! We have an algebraic equation with the variable <em>n</em>. We want to solve for n. Therefore, we need to simplify the expression as much as we can.

To do this, we're going to notice we have two like terms in the equation:

  • 71
  • 1

These two terms can be combined to make one term. In order to do this, we're going to check which side of the equation has two terms.

  • Left side → 1 term
  • Right side → 2 terms

We are going to then check the sign of the constant. As a reminder, constants are numbers without a variable attached to them.

We see our constant is 1 on the right side and it is positive due to it being added to 10<em>n</em>. Therefore, we are going to do the opposite and subtract it from 71.

  • 71 - 1 = 70

This leaves us with a more simplified equation: 70 = 10n.

To make things easier, we're going to use the commutative property and switch the terms around. This will give us 10n = 70. It is easier to operate when our variable term is on the left side.

Now, we need to get our variable by itself. A coefficient is multiplying the variable by that value, so to reverse that, we must divide.

In addition to that, what we do on one side of the equation must be done on the other side of the equation.

\displaystyle \frac{10n}{10} = \frac{70}{10}

This simplifies to n = 7, which is our final answer.

1.) The deer population increases at a rate of 3% per year. There are 1253 deer this year. Write a function that models the deer
BabaBlast [244]
Exponential growth/decay rule with general function is:<span>y=y(0)<span>e<span>kt</span></span></span> with k is growth/decay constant rate.
(1) Deer population function y(0) = 1253 k
= 3% t
 = 6 (years)
  y(6) = 1253 . e^(0.03*6) ~ 1500 (deers)
: 1496 deers
 (2) Growth factor b is rate 9.5% = 0.095

Naya [18.7K]

Answer:

101010 classmates can't tell their dreams.

Step-by-step explanation:

I'm not sure what the question is, but if it is an average thing than 444 of 555 is 80 percent, so if that is what it wants 404040 of the students can share their dreams, and 101010 can't.

Hope this helps!
