A scientist uses a submarine to study ocean life.
She begins 83 feet below sea level.
• After descending for 5 seconds, she's 151 feet below sea level.
Find the rate of change in the submarine's elevation in feet per second. If
necessary, round your answer to the nearest tenth
Answers
The scientist descends from 83 feet below sea level to 151 feet below sea level, a change in depth of 151 - 83 = 68 feet. This change occurs over a time of 5 seconds.
The rate of change in depth, or the speed at which the submarine is descending, is given by the ratio of the change in depth to the time taken:
Rate of change in depth = (final depth - initial depth) / time taken
Rate of change in depth = (151 ft - 83 ft) / 5 s
Rate of change in depth = 13.6 ft/s (rounded to one decimal place)
Therefore, the rate of change in the submarine's elevation is 13.6 feet per second.
describe how to estimate the regression function (equivalently, a,b) by the least-squares principle. notes: you only need to provide a description. this is an example of a nonlinear regression model.
Answers
The estimates are used to construct the estimated regression equation:
ŷ = b0 + b1x.
What is the estimation of the regression function?Regression analysis is typically performed for one of two reasons: to estimate the influence of some explanatory variable on the dependent variable or to predict the value of the dependent variable for individuals for whom some information about the explanatory variables is available. Y = mX + b is the equation for simple linear regression, where X is the predictor (independent) variable, m is the estimated slope, and b is the estimated intercept. An estimated regression equation is created using these estimates: ŷ = b0 + b1xA straight line is a good approximation to the relationship between y and x on the graph of the estimated regression equation for simple linear regression.Therefore, the estimates are used to construct the estimated regression equation: ŷ = b0 + b1x.

Suppose are running a study/poll about the probability of catching the flu this year. You randomly sample 142 people and find that 69 of them match the condition you are testing. Suppose you have the following null and alternative hypotheses for a test you are running: H 0 : p = 0.54 H a : p < 0.54 Calculate the test statistic, rounded to 3 decimal places
Answers
The test statistic of null and alternative hypotheses for a test is 0.811.
69 of the 142 persons that were randomly chosen from a sample are found to meet the condition we are testing.
The sample proportion phat = 69 ÷ 142 = 0.489
n = 69
p = 0.54
the following are your test's null and alternate hypotheses:
\(H_0\) : p = 0.54
\(H_a\) : p < 0.54,
test statistic,
z = (phat - p) ÷ √(p × (1 - p) ÷ n)
z = (0.489 - 0.54) ÷ √((0.79 × 0.21) ÷ 42) = 0.811
A test statistic is a figure obtained from a statistical analysis. It explains how distant the observational values seem to be from the null hypothesis, which states that there is no correlation between the variables or distinction between the sample groups.

2.y=1x+21

4.y=1x1+2
Answers
Answer:
4. y = |x| + 2
Step-by-step explanation:
"g(x) = |x| + k" means that f(x) will be translated however many units up or down depending on k. If k is positive, the graph will translate up. If k is negative, the graph will translate down. Because we need to translate up, the value of k needs to be positive. The best answer choice is choice 4, y = |x| + 2.
We can eliminate choices 1 and 2 because the way the equations are set up are for the horizontal translations.
g(x) = |x - h| are for horizontal translations.
g(x) = |x| + k are for vertical translations.
The third choice is wrong as well because k is negative, not positive.

Answers
The graph of f(x) starts at negative infinity as x approaches 2 from the right and grows indefinitely as x approaches infinity, exhibiting a vertical asymptote at x = 2.
The logarithmic function f(x) = ln(x - 2) is defined as the natural logarithm of the quantity (x - 2). It represents the power to which the base, e (approximately 2.718), must be raised to obtain the difference between x and 2.
The function is only defined for x values greater than 2, as the argument of the natural logarithm must be positive. It is a monotonically increasing function, meaning it always increases as x increases.

In the rhombus WXYZ, < WXY = 84° . find < WZY and < XWYI don't really understand how to do this could you explain?
Answers
Answer:
84° and 48°
Step-by-step explanation:
1st of all, the inner angle of rhombus would total up into 360° and the opposite for each angle is equal to each other.
As ∆WXY = 84°, so
∆WZY = 84°
Any diagonal line in the rhombus would make the angle get divided equally i.e ∆XWZ
So find ∆XWZ first.
∆XWZ = (360° - 84° - 84°) ÷ 2
= 192° ÷ 2
= 96°
∆XWY = 96° ÷ 2
= 48°
A probability is a numerical value that indicates the chance, or likelihood, of a specific event occurring.

Answers
This statement is true
A probability is a numerical value that indicates the chance, or likelihood, of a specific event occurring. Probability is the measure of the likelihood of a random event happening, and it is expressed as a number between 0 and 1, with 0 implying that the event would never occur and 1 implying that it is certain to happen.
The probability of an event happening is referred to as its likelihood. Probability can be expressed as a fraction, percentage, or decimal, and it is a vital tool in statistics. It is frequently utilized in mathematics to estimate real-world situations that involve random variables such as coin flips, weather patterns, stock market trends, and even sporting events.
