Answer:Blue whale

Step-by-step explanation:

The blue whale goes  an extra kilometer faster

The Mako shark faster at top cruising speed and by 20km/h.

Given that,

Based on the above information, the calculation is as follows:

We know that

\(Speed = \frac{Distance}{Time}\)

For Mako shark,

\(= \frac{4}{\frac{1}{10} }\)

= 40 km/h

For Blue whales

\(= \frac{5}{\frac{1}{4} }\)

= 20 km/h

Based on the above calculations we can say that the Mako shark should be faster and by 20 km/h.

If the Uptown bank lends $22200 at 6.9% , then the amount of each monthly payment is (d) $530.57  .

The amount that Uptown bank will lend is = $22200 ,

the rate is = 6.9% ,since it is compounded monthly ,

So , monthly rate is = 6.9%/12 = 0.00575 ,

the time for which the car is financed is = 48 months ,

So , to calculate the monthly payment, we can use the formula:

⇒ P = (PV × r)/(1 - (1 + r)⁻ⁿ)

Where P is monthly payment, PV is present value of loan, r = monthly interest rate, and n = number of payments.

In this case, PV = $22200, r = 6.9%/12 = 0.00575 (monthly interest rate), and n = 48.

Substituting these values in monthly payment formula, we get:

⇒ P = (22200×0.00575)/(1 - (1 + 0.00575)⁻⁴⁸)

⇒ P ≈ $530.57

Therefore, the monthly payment will be approximately $530.57 . The correct answer is (d) $530.57 .

The required value of the given function is (f ⋅ g)(4) = 130.

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

The functions are given in the question, as follows:

f(x)=3x+1 and g(x)=x²-6

(f ⋅g)(x) is the composition of the functions f and g, which means f(x) × g(x).

(f ⋅ g)(x) = f(x) × g(x)

So, substituting x = 4:

(f ⋅ g)(4) = f(4) × g(4)

= (3 × 4 + 1)×(4² - 6)

= 13 × 10

= 130

So, (f ⋅ g)(4) = 130.

The probability of an adult getting a NEG result and truly having tuberculosis is 0.01725, which is closest to option (A) 0.0373.

Let's use the following notation:

P(TB) represents the probability that an adult has tuberculosis, which is given as 0.05.

P(POS|TB) represents the probability that the test is positive given that an adult has tuberculosis, which is given as 0.746.

P(NEG|TB) represents the probability that the test is negative given that an adult has tuberculosis, which is 1 - P(POS|TB) = 0.254.

We are asked to find the probability of an adult getting a NEG result and truly having tuberculosis, which can be calculated using Bayes' theorem as follows:

P(TB|NEG) = P(NEG|TB) * P(TB) / P(NEG)

We can calculate P(NEG) using the law of total probability, which considers the two possible cases for an adult: having tuberculosis (TB) or not having tuberculosis (TB').

P(NEG) = P(NEG|TB) * P(TB) + P(NEG|TB') * P(TB')

= 0.254 * 0.05 + 0.7653 * 0.95

= 0.7352

Now we can substitute the values into Bayes' theorem:

P(TB|NEG) = 0.254 * 0.05 / 0.7352

= 0.01725

Therefore, the probability of an adult getting a NEG result and truly having tuberculosis is 0.01725, which is closest to option (A) 0.0373.

No, the F-test statistic cannot be less than 1 when it represents the larger of two sample variances.

The F-distribution is always a positive distribution with a range of values greater than zero. The F-test value is always greater than or equal to 0, but it is not always less than or equal to 1.

The numerator, representing the bigger sample variance, is always greater than or equal to the denominator, representing the smaller sample variance. Consequently, the F-ratio, which is the ratio of the larger to the smaller variance, is always greater than or equal to 1. Thus, an F-test statistic that is less than 1 is mathematically incorrect.

Therefore, an F-test statistic is always a positive number that is greater than or equal to zero and greater than or equal to 1. This is because the numerator of an F-distribution is always greater than or equal to the denominator.

No one because odd functions are symmetric about the origin.

It is a function such that f (x) =f (x) with the sign reversed but the absolute value unchanged if the independent variable's sign is reversed.

If f(x) Equals f(x) for every x, a function is odd. An odd function's graph will be symmetrical around the origin.

For instance, f(x) = x3 is an odd number. That is, the function on one side of the x-axis is sign inverted in relation to the function on the other side, or graphically, symmetric about the origin.

Answer: B

Step-by-step explanation:

To determine whether the series ∑(n=1 to infinity) 7n/n is convergent or divergent, we can apply the ratio test. The ratio test helps us determine the convergence or divergence of a series by examining the limit of the ratio of consecutive terms.

In this case, let's calculate the ratio of consecutive terms using the formula for the ratio test:

lim(n→∞) |(7(n+1)/(n+1))/((7n/n)|

Simplifying the expression, we get:

lim(n→∞) |7(n+1)/n|

As n approaches infinity, the limit evaluates to:

lim(n→∞) |7(n+1)/n| = 7

Since the limit is a finite positive value (7), which is less than 1, the ratio test tells us that the series is convergent.

However, you mentioned identifying an (term) in the series, and it seems there may be an incomplete part of the question. Please provide additional information or clarification about identifying an term in the series so that I can provide a more specific answer.

The 106° measure of arc \(m\widehat{HJ}\) and the length of the chords \(\widehat{FH}\) and \(\widehat{JH}\), which are the same, indicates that m∠G = 21° and ΔFGH is not isosceles. The correct option is option C;

C. The measure of ∠G is 21°, and triangle FGH is not isosceles

An isosceles triangle is a triangle that have two sides of the same length and two angles of the same measure.

According to the outside angle to a circle theorem, the measure of the outside angle ∠G formed by the secant GJ and the tangent GF is equal to the difference of the measures of the arcs \(m\widehat{F'KJ}\), and arc \(m\widehat{FH}\) divided by 2.

\(m\widehat{F'KJ}\) = 360° - \(m\widehat{FH}\) - \(m\widehat{HJ}\)

\(\widehat{FH}\) = \(\widehat{JH}\)

\(\widehat{FH}\) ≅ \(\widehat{JH}\)

The lengths of the chord intercepted by congruent arcs are congruent.

Therefore; \(\widehat{JH}\) ≅  \(\widehat{FH}\)

Which indicates;

\(m\widehat{JH}\) = 106° = \(m\widehat{FH}\)

\(m\widehat{F'KJ}\) = 360° - 106° - 106° = 148°

m∠G = (\(m\widehat{F'KJ}\) - \(m\widehat{FH}\)) ÷ 2

m∠G = (148° - 106°) ÷ 2 = 21°

\(m\widehat{F'KJ}\) = 148°

m∠FHJ = 148° ÷ 2 = 74° (Angle at the center is twice angle formed at the circumference)

∠FHJ = ∠HFG + ∠G (exterior angle to triangle ΔFGH)

∠HFG = ∠FHJ - ∠G

Therefore; m∠HFG = 74° - 21° = 53°

m∠HFG = 53°

m∠FHG = 180° - 74° = 106° (linear pair angles property)

The correct option is option C.

the original number Juan started with was 6.

Let "x" represent the original number. Juan first adds 2 to the original number, which can be expressed as (x + 2). He then multiplies this by 2, resulting in 2(x + 2). Next, he subtracts 2 from this product: 2(x + 2) - 2. Finally, he divides the resulting number by 2, giving us the equation [(2(x + 2) - 2) / 2] = 7.
Now, let's solve for the original number, x:
1. Simplify the equation by distributing the 2: [2x + 4 - 2] / 2 = 7
2. Combine the constants: (2x + 2) / 2 = 7
3. Multiply both sides by 2 to remove the denominator: 2x + 2 = 14
4. Subtract 2 from both sides: 2x = 12
5. Divide both sides by 2: x = 6

To use Theorem 4.6 and find the values of k for which the matrix A is invertible, we first need to know the elements of the matrix A. Please provide the matrix so I can help you determine the values of k.

Theorem 4.6 states that a square matrix A is invertible if and only if its determinant is nonzero. Therefore, to find all values of k for which A is invertible, we need to find the determinant of the matrix and set it equal to zero.

Let A be the given matrix. We have:

det(A) = (k-2)(-1)(k-1) + (-1)(k-1)(2k-3) + (k-2)(2k-3)(k-1)
det(A) = -k^3 + 5k^2 - 5k + 3

Setting det(A) equal to zero and solving for k, we get:

-k^3 + 5k^2 - 5k + 3 = 0

Using synthetic division or factoring, we can find that k = 1 is a root of this equation. Dividing by (k-1), we get:

-(k^2 - 4k + 3) = 0

Factoring again, we get:

-(k-1)(k-3) = 0

Therefore, the values of k for which A is invertible are k = 1 and k = 3.

A property of an isosceles triangle, which is the base angles of the are equal, can be used to show that ΔBCD us an isosceles triangle.

There are two equal edges and two equivalent angles in an isosceles triangle. The Greek words iso (identical) and Skelos are the source of the name (leg). Equilateral triangles are those in which all of the sides are equal, whereas scalene triangles are those in which none of the sides are equal.

The characteristics of an isosceles triangle are as follows:

Let assume,

∠DAB = ∠A,

∠DCB = ∠C,

∠ABC = ∠B

The steps to show that ΔABD is an isosceles triangle are as follows;

∠ABD = 72° = ∠ADB :- Base angles of the isosceles triangle ΔABD

∠A + ∠ABD + ∠ADB = 180° (angle summation property)

∠A = 180° - (∠ABD + ∠ADB) = 180° - (72° + 72°) = 36°

∠A = ∠C :- Base angles of the isosceles triangle ΔBDC

∠ADB = ∠C + ∠DBC :- Exterior angle of a triangle theorem

72° = ∠C + ∠DBC

∠BDC = 72° + ∠A

∠DBC + ∠BDC + ∠C = 180° (angle summation property)

∠DBC = 180° - (∠BDC + ∠C) = 180° - (72° + 36° + 36°) = 36°

∠DBC = 36° = ∠C

In ΔBCD, ∠DBC = ∠C
