Stem and leaf plots are used to visualize data, graphically

The true statement is (b) There are 30 buildings in the county that are taller than 50 feet.

<h3>How to interpret the stem and leaf plot</h3>

From the stem and leaf plot, we have that the number of leaves is 30

This means that, the total frequency of the dataset is 30

So, the number of buildings taller than 50 feet is 30

Hence, the true statement is (b) There are 30 buildings in the county that are taller than 50 feet.

When we evaluate a logarithm, we are finding the exponent, or power x, that the base b, needs to be raised so that it equals the argument m. The power is also known as the exponent.

$5^2 = 25 \to \log_5(25) = 2$

The value of b must be positive and not equal to 1

The value of m must be positive

If 0 < m < 1, then x < 0

A logarithmic equation is an equation with a variable that includes one or more logarithms.

===============================================

Explanation:

Logarithms, or log for short, basically undo what exponents do.

When going from $5^2 = 25$ to $\log_5(25) = 2$ , we have isolated the exponent.

More generally, we have $b^x = m$ turn into $\log_b(m) = x$

When using the change of base formula, notice how

$\log_b(m) = \frac{\log(m)}{\log(b)}$

If b = 1, then log(b) = log(1) = 0, meaning we have a division by zero error. So this is why $b \ne 1$

We need b > 0 as well because the domain of y = log(x) is the set of positive real numbers. So this is why m > 0 also.

What is the range of f(x)=4•0.5^x?

VikaD [51]

The range is the output, which would be the Y value.

The Y value would be calculated based on the input value for x.

any positive number raised to any value of x would be a positive number so 0.5^x would always be positive.

That would be multiplied by 4, which is a positive value, so the output ( Y value) would always be positive.

The range for this would be (0,∞)

attashe74 [19]

Answer:

$-1\frac{7}{10}$

Step-by-step explanation:

Convert the mixed numbers into improper fractions: $\frac{-17}{8}$ ÷ $\frac{5}{4}$
Apply the fractions formula for division: $\frac{-17*4}{8*5} = \frac{-68}{40}$
Simplify: $-1\frac{7}{10}$

Answer:

They studied for a little more than an our. A

Step-by-step explanation:

Because if you multiply 4 on 2/3 you get 8/12, then add 8/12 and 7/12 together to get 15/12 simplified 1 3/12.
