3. 8

4. 1.44

5. 2

6. 4

Step-by-step explanation:

Use cross multiplication and then divide by the coefficient of x.

Here is how to solve number 1. Solve the rest of them like this.

2.5(15) = 5x

37.5 =5x

5 5

The graph shows the exponential regression model for data representing a rabbit population after x years. Which is true of the r

tamaranim1 [39]

Answer: The graph of the regression model can be used to predict the population size for any number of years in the future.

Step-by-step explanation:

Since with help of the given graph, we can say that

The graph of the regression model is applied for the every real value of x.

Thus the statement The graph of the regression model is limited to whole-number values for x is false.

Also, the range of an exponential function is always a set of real number.

Therefore, The graph of the regression model is limited to whole-number values for y is false.

Since, for 1 year, the approximate population is given,

Therefore, The graph of the regression model cannot be used to approximate the population size for year 1 is false.

Again according to the given graph we can say that we can get the population for any number of year.

Thus, The graph of the regression model can be used to predict the population size for any number of years in the future is true.

Firlakuza [10]

Answer:

Step-by-step explanation:

Lisha is making headbands using ribbon.

each one requires 15.5 inches of ribbon

For 12 headbands Lisha need to buy ribbon = 15.5 × 12

= 186 inches

Therefore, Lisha will need to buy 186 inches ribbon.

160 inches ribbon is not sufficient to make 12 headbands. She will need to buy 186 inches or more.

2^3+5x(6+4)÷2, for MATH LIB

Lynna [10]

Evaluate 2^3+5x(6+4)÷2 following Order of Operations rules (PEMDAS):

Work within parentheses is done first, followed by exponentiation, and then mult. and div., and finally add'n. and subtr'n.

Thus, 2^3+5x(6+4)÷2 becomes 2^3+5x(10)÷2

8 + 50x/2

Tyrone went to a basketball game and bought a jersey that was on sale at a 30% discount. He also bought a hat that cost $37.89.

Dmitry [639]

Answer:

Jersey cost (without discount)= $65

Step-by-step explanation:

<u>First, we need to determine how much he spent on the jersey:</u>

Jersey cost (with discount)= 83.39 - 37.89

Jersey cost (with discount)= $45.5

<u>Now, the original cost of the jersey:</u>

Jersey cost (without discount)= discount cost / (1 - discount)

Jersey cost (without discount)= 45.5 / 0.7

Jersey cost (without discount)= $65
