Mathematics
1 answer:
Bond [772]2 years ago
8 0

Answer:

84 couples

Step-by-step explanation:

First add the number of couples that have only one spouse that prefers dramas.

23+39+37+27=126

126 couples out of 250 prefer dramas.

126/250=.56 or 56 percent

To find the answer by making a prediction based on this data, you would find 56% of 150.

150x.56=84 out of the additional 150 surveyed couples will have one spouse that prefers a drama.

Alika [10]

Answer:

2

Step-by-step explanation:

Let's change the base to base 10 (log10(x) = log(x)).

logb(a) = log(a)/log(b)

log3(3²) =log(3²)/log3

Knowing that log(aⁿ) = n*log(a)

log(3²)/log3 = 2*log(3)/log(3)

So, we can simply log(3)/log(3) = 1

log3(3²)  = 2

Which number line correctly shows 1.5 + 2.5?
GrogVix [38]

Answer:

We conclude that the first line number represents 1.5 + 2.5.

Step-by-step explanation:

Given the expression

1.5 + 2.5

It means the first segment must represent 1.5 units starting from 0.

Since we have to add 2.5 to 1.5, so the next segment must represent 2.5 units, starting from 1.5

Combining them would make

1.5 + 2.5=4

Now, if we observe the first number line,

  • The first arrow represents the 1.5 units starting from 0.
  • The second arrow represents the 2.5 units starting from 1.5.
  • The combined units of both arrows represent the length of 4 units. i.e. 1.5 + 2.5 = 4

Thus, we conclude that the first line number represents 1.5 + 2.5.

The correct line number is also attached below.

Two students in your class, Tucker and Karly, are disputing a function. Tucker says that for the function, between x = -3 and x
trasher [3.6K]
This can occur through a parabola that has zeroes at x = 3 and x = -3. There is no rate of change because the y values do not change at those points because they are both 0. Karly can be correct because that turning point can be a vertex of a parabola. The parabola's function would increase until it reaches it's highest point and then go back down again. In this way, Karly and Tucker can both be correct.

Hope this helps :)
