A quadratic function can have up to two x-intercepts.

An x-intercept of a quadratic function is also called a zero of the function.

Step-by-step explanation:

None needed.

The true statement is

An x-intercept of a quadratic function is also called a zero of the function.

A quadratic function can have up to two x-intercepts.

A quadratic polynomial function has one or more variables and a variable with a maximum exponent of two. It is also known as the polynomial of degree 2 because the second-degree component in a quadratic function is the biggest degree term. A quadratic function must contain at least one term of the second degree. It possesses algebraic qualities.

we have,

The x-intercepts of quadratic functions,

The standard form of quadratic equation is

ax² + bx + c = 0

The zeroes of the quadratic functions are the values of x, which is also known as the x-intercept.

Because the degree of the polynomial is 2, there will be at least two x-intercept values.

The x-intercept is the x position at which the value of y is zero.

Let x = a be an x-intercept, and the function factor is (x - a).

Cost of over reserving full cost tickets, Co = $440 ( empty seats as we cannot get even the discounted revenue)

Cost of under reserving Cu = 770-440 = $330 ( because you sell more discounted tickets)

Now critical ratio = Cu / (Cu+Co) = 330/770 = 0.42857

To determine whether there is enough evidence to reject the claim of the state Department of Transportation, a hypothesis test needs to be performed. The null hypothesis (H0) is that the mean wait time is 6 minutes or less, while the alternative hypothesis (H1) is that the mean wait time is greater than 6 minutes. Using a one-sample t-test, the test statistic is calculated and compared to the critical value obtained from the t-distribution table or calculator. In this case, the test statistic is greater than the critical value, indicating that there is enough evidence to reject the null hypothesis.

To determine whether there is enough evidence to reject the claim of the state Department of Transportation, we need to perform a hypothesis test.

Hypotheses:

Let:

μ be the mean wait time for various services at different locations.

The null hypothesis (H0) is that the mean wait time (μ) is 6 minutes or less:

H0: μ ≤ 6
The alternative hypothesis (H1) is that the mean wait time (μ) is greater than 6 minutes:

H1: μ > 6

Test statistic:

We will use a one-sample t-test since the population standard deviation is unknown.

The test statistic (t) is calculated using the formula:

t = (Xbar - μ)/(s/√(n))

Where:

Xbar is the sample mean - 10.3 minutes,

μ is the claimed mean - 6 minutes,

s is the sample standard deviation - 8.0 minutes, and

n is the sample size - 34.

Critical value:

To find the critical value, we need to determine the rejection region using the significance level (alpha) of 0.01 and the degrees of freedom (df) which is n - 1 = 33.

From the t-distribution table or calculator, the critical value for a one-tailed test at alpha = 0.01 and df = 33 is approximately 2.449.

Conclusion:

The test statistic (t) = (10.3 - 6)/(8.0/√(34)) = 3.720.

Since the test statistic (t) = 3.720 > 2.449 (the critical value), we have enough evidence to reject the null hypothesis.

Therefore, we can conclude that there is sufficient evidence to reject the claim of the state Department of Transportation at alpha = 0.01.

B. 3 by 12

Step-by-step explanation:

The rectangle is four times as long as it is wide,

(3 times 4=12)

and has an area of 36

(3 times 12=36)

so this is the correct answer.

If the area of the given rectangle is 36 square inches, then the length of rectangle is 12 inches and the breadth of rectangle is 3 inches.

"Area is the quantity that expresses the extent of a region on the plane or on a curved surface."

"A rectangle is a shape with four straight sides and four angles of 90 degrees (right angles)."

Area of rectangle = 36 square inches

Let the width of rectangle be y

Length of rectangle be 4y

Area of rectangle = length × breadth

y×4y = 36

[tex]4y^{2} = 36[/tex]

[tex]y^{2}=9\\y=\sqrt{9}[/tex]

[tex]y=3[/tex]

Hence, the width of the rectangle is 3 inches and the length of the rectangle is 12 inches.

Step-by-step explanation:

A secant is a line that intersects a circle in exactly two points. When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.

The formation of secant lines that intersect within a circle is related when a secant and a tangent or two tangents intersect each other outside a circle.

A secant line is a straight line that connects two points on a curve. The secant line approaches a tangent line when the two points are drawn together.

So, If a tangent and a secant, or two tangents intersect at the exterior side of a circle, the angle created has a measure equal to one-half the positive difference between the intercepted arcs' measures.

The length of side DE in the right triangle shown is 4.24 units.

We can use the Pythagorean Theorem to solve for the length of DE, since we know the lengths of the other two sides.

The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

The hypotenuse of the triangle is DE, and the other two sides are DF and EF. We know that DF = EF = 3 units. Therefore, we can set up the following equation:

[tex]DE^2 = DF^2 + EF^2[/tex]

Substituting in the known values, we get:

[tex]DE^2 = 3^2 + 3^2[/tex]

[tex]DE^2 = 9 + 9[/tex]

[tex]DE^2 = 18[/tex]

Taking the square root of both sides, we get the length of DE:

DE = √18

DE ≈ 4.24 units

Therefore, the length of side DE in the right triangle shown is 4.24 units.

The t-statistic is calculated as: -6.70

What is the test statistic?

The appropriate test to conduct at the alpha equals 0.01 level of significance is a one-tailed t-test.

The null hypothesis is that the mean hippocampal volume of adolescents with alcohol use disorders is equal to 9.02 cm cubed, while the alternative hypothesis is that the mean hippocampal volume is less than 9.02 cm cubed.

Thus:

H₀: μ = 9.02 cm³

Hₐ: μ < 9.02 cm³

The t-statistic is calculated from the formula:

t = (x - μ)/(σ/√n)

t =  (8.02 - 9.02) / (0.7/√(22))

= -6.70.

Therefore, the t-statistic is -6.70

Answer:

We conclude that the mean number of thunder days is less than 92.

Step-by-step explanation:

We are given that Historically, a certain region has experienced 92 thunder days annually.

Over the past fifteen years, the mean number of thunder days is 72 with a standard deviation of 38.

Let [tex]\mu[/tex] = mean number of thunder days.

So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu \geq[/tex] 92 days     {means that the mean number of thunder days is more than or equal to 92}

Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] < 92 days     {means that the mean number of thunder days is less than 92}

The test statistics that would be used here One-sample t test statistics as we don't know about the population standard deviation;

                       T.S. =  [tex]\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }[/tex]  ~ [tex]t_n_-_1[/tex]

where, [tex]\bar X[/tex] = sample mean number of thunder days = 72

             s = sample standard deviation = 38

            n = sample of years = 15

So, test statistics  =  [tex]\frac{72-92}{\frac{38}{\sqrt{15} } }[/tex]  ~ [tex]t_1_4[/tex]

                               =  -2.038

The value of z test statistics is -2.038.

Since, in the question we are not given with the level of significance so we assume it to be 5%. Now, at 5% significance level the t table gives critical value of -1.761 at 14 degree of freedom for left-tailed test.

Since our test statistics is less than the critical value of t as -2.038 < -1.761, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region due to which we reject our null hypothesis.

Therefore, we conclude that the mean number of thunder days is less than 92.

Step-by-step explanation:

1 mile = 1.6 km

1 km = 1000 m

1.6 * 1000 = 1600, So to swim 1 mile, she must swim 1600 m

She has already swam 60 lengths which is 1500 m because 60 (the number of lengths)*25 (the length of the pool) = 1500.

1600 (the amount she needs to swim) - 1500 (the amount she has already swam) = 100.

She needs to swim 100 m more, which is 4 lengths because 100/25 = 4.
