Answer:

D. linear; y = –x – 1

Step-by-step explanation:

Linear; y=-x - 1

The slope is negative since it’s decreasing. So it’s not the first equation. It’s not a quadratic equation because there is no forming U shape for this data. It’s not a exponential function because the slope is not 3 and a exponential function is in the form y=a(b)^x

Answer:

The correct answer is D) linear; y = –x – 1

Step-by-step explanation:

To find this, use any values in the table and it will produce a true statement. This is how we check to see if a model is correct. See the two examples below for proof.

(4, 5)

y = -x - 1

-5 = -4 - 1

- 5 = -5 (TRUE)

(0, -1)

y = -x - 1

-1 = 0 - 1

-1 = -1 (TRUE)

A random sample of 145 students is chosen from a population of 4,250 students. The mean IQ in the sample is 130, with a standard

snow_tiger [21]

Answer:

Approximately, the 90% confidence interval for the students' mean IQ score is between 129.045 - 130.956

Step-by-step explanation:

The formula to use to solve this question is called the Confidence Interval formula.

Confidence interval =

x ± z × ( σ/ (√n) )

Where:

x = the sample mean = 130

z = the z-value for 90% confidence = 1.645

σ = standard deviation = 7

n = sample size = 145

130 ± 1.645 × (7/√145)

130 ± 0.9562687005

130 - 0.9562687005 = 129.0437313

130 + 0.9562687005 = 130.9562687005

Therefore, approximately, the 90% confidence interval for the students' mean IQ score is between 129.045 - 130.956

Three ounces of broiled ground beef contains 245 calories. Is this the number of calories directly or inversely proportional to

aalyn [17]

Answer:

The number of calories are directly proportional to the number of ounces.

Step-by-step explanation:

We can relate these values as:

Let x be the calories in 4 ounces of broiled hamburger.

$\frac{3}{245} =\frac{4}{x}$

=> $3x=4\times245$

=> $3x=980$

Dividing by 3 on both sides;

x = 327 approx

We can see that 4 ounces contain 327 calories.

Per ounce will have $327/4=81.75$ calories.

As the quantity of hamburger increases, the calories count also increases.
