Answer:

24

Step-by-step explanation:

= 10x+y=4(x+y)

= 10x-4x=4y-y

= 6x=3y

(÷2) = (2x=y)----- eq.1

According to the quest:-

Case.2-- the number is also equal to 3 times the product of the digits.

10x+y=3xy

Substitute the value of y=2x in place of y.

We get, 10x+2x=(3x)(2x)

= 6x²-12x=0

= 6x(x-2)=0

= 6x=0 so, x=0 or x-2=0 so, x=2.

Consider eq.1:- 2x=y

= 2(2)=y so y=4

OR

= 2(0)=y so y=0

So we take x=2 and y=4

The number:- 10x+y

= 10(2)+4

= 24

Answer:

There will be 20 grams of fat in 10 pounds of chicken.

Step-by-step explanation:

Based of the pattern you can tell that the Grams of fat will always be double the amount of pounds.

2 grams of fat in 1 pound

9 grams in 4.5 pounds

So:

10 * 2 = Grams of fat

10 * 2 = 20 Grams of fat.

So there will be 20 grams of fat in 10 pounds of chicken.

Answer:

18/23=0.7826

0.7826 rounded to the nearest hundredth is 0.78

Your answer is 0.78

Answer:

0.78

Step-by-step explanation:

All you have to do is 18 divided by 23. That equals 0.78260869565 which when rounding to nearest hundreth is equal to 0.78 because hundreth is to the second decimal place.

27-25=2

so her absolute error was 2 students

divide the answer by 100 to get the percentage error.

percentage error = absolute error/ 100

2/100=0.02%

therefore her percentage error is 0.02%.

Answer:

Height = 17.3 ft

Step-by-step explanation:

The diagram depicts a right angled triangle and will be solved using Pythagoras theorem.

Represent the length of the ladder with L

L = 20

Represent the distance between the ladder and thr building with B

B = 10

Represent the height with of the building with H

Solving for H, we have

H² + B² = L²

H² + 10² = 20²

H² + 100 = 400

H² = 400 - 100

H² = 300

H = √300

H = 17.320508075688772

H = 17.3 (approximated)

Hence, the height of the building is 17.3 ft

Answer:

The range of g(x) is [5, ∞) ⇒ (a)

Step-by-step explanation:

The range of the function is the values of y which corresponding to the values of x (domain)

∵ [tex]g(x)=5+\sqrt{4-x}[/tex]

∵ There is no square root for negative values

∴ 4 - x ≥ 0

→ Add x to both sides

∴ 4 - x + x ≥ 0 + x

∴ 4 ≥ x

→ that means x is smaller than or equal to 4

∴ x ≤ 4

→ The greatest value of x = 4

∴ The domain of g(x) = {x : x ≤ 4} ⇒ (-∞, 4]

→ At x = 4

∵ g(4) = 5 + [tex]\sqrt{4-4}[/tex]

∴ g(4) = 5 + 0

∴ g(4) = 5

→ That means the smallest value of y = 5 because  [tex]\sqrt{4-x}[/tex] is always

   give a positive value which add to 5

∴ The range of g(x) is {y : y ≥ 5} ⇒ [5, ∞)

The right answer is (a)

Answer:

The third one is the one that's not correct.

Step-by-step explanation:

|8| is just 8 but |-9| is 9. So in that case |8| is not greater than 9.

Answer: it is the first one

Step-by-step explanation: the third one is not correct cause it is obviously less than 9

The total cash due at signing is, $15300

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, The MSRP of the car is,  $27,500.

Now, The monthly payment = $425 and it is for 36 months,

Therefore, The total monthly downpayment is, 36×425 = $15300.

So, The total cash due at signing is, $15300 the monthly installments.

Answer:

The side length of the rectangular prism is 2 feet

Step-by-step explanation:

The volume of the rectangle prism = L × W × H, where

If the 3 dimensions of the rectangular prism are equal, then its

volume = L × L × L = L³

In the question

∵ The rectangular prism has a volume = 8 ft³

∵ The question asks for its side length

→ That means all dimensions are equal

∴ V = L³

→ Substitute V by 8

∴ 8 = L³

→ Take cube root for both sides

∴ ∛8 = ∛(L³)

∴ 2 = L

∴ L = 2 ft

The side length of the rectangular prism is 2 feet

For English :

Mean score(m1) = 6.4

Standard deviation (s1) = 2.0

For Science :

Mean score (m2) = 7.0

Standard deviation (s2) = 1.6

n = number of observations = 5

Correlation Coefficient (r) :

r = 1/(n - 1) Σ[((X - m1) / s1) * ((Y - m2) /s2)]

(-0. 2 * 0.625) + (-0.7 * - 1.25) + (1.3 * - 0.625) + (-1.2 * 0) + (0.8 * 1.25) = 0.9375

r = 0.9375/(5-1)

Answer:

Benford’s law states that the probability that a number in a set has a given leading digit, d, is

P(d) = log(d + 1) - log(d)  

The division property of logarithm should be use to make it as a single logarithm  

P(d) = log ( (d + 1)/ d)  

So the probability that the number 1 is the leading digit is

P(1) = log ( ( 1+1)/ 1)

P(1) = log ( 2)

P(1) = 0.301

Step-by-step explanation:

Answer:

Use the quotient property to rewrite the expression. Write the difference of logs as the quotient log((d+1)/d). Substitute 1 for d to get log(2).  Since log(2) = 0.30, the probability that the number 1 is the leading digit is about 30%.

Answer:

See Explanation

Step-by-step explanation:

The question has missing details.

However, I'll make the following assumptions:

[tex]Biscuits = 20[/tex]

[tex]Difference = 2[/tex] (Fewer/Extra)

To solve your question, simply change the numbers

Required

Determine the range of the biscuits

To calculate the number of minimum biscuits, we have:

[tex]Minimum = Biscuits - Difference[/tex]

[tex]Minimum = 20 - 2[/tex]

[tex]Minimum = 18[/tex]

To calculate the number of maximum biscuits, we have:

[tex]Maximum = Biscuits + Difference[/tex]

[tex]Maximum = 20 + 2[/tex]

[tex]Maximum = 22[/tex]

The missing data is defined in the attached file please find it.

Given:

                                            Admission Status

[tex]\left\begin{array}{ccccc}Ethnography &Acceptable \ Approval &Waitlisted & Turned \ Away & Total\\\\ Hispanic/ Black & 51 &206&143 & 400 \\Asia &57&289&100&446\\White& 62&222&145&429\\ Total & 170& 717& 388& 1275\end{array}\right \\\\\\[/tex]

In point A:

The overall percent of applicants, which is Asia:

[tex]= \frac{446}{1275} \\\\ = 0.3498039 \approx 34.98 \%[/tex]

In point B:

The overall percent of the students, who admitted to Asia:

[tex]P(accepted\ Asian) = P( \frac{Placcepted \ Asian}{Asian})[/tex]

                              [tex]= \frac{\frac{57}{1275}}{\frac{446}{1275}} \\\\= \frac{57}{1275} \times \frac{1275}{446} \\\\= \frac{57}{446} \\\\= 0.1278027\approx 12.78 \%[/tex]

In point C:

The Asian percentage approved:  

[tex]P(Asian/accepted) =\frac{P(accepted, Asian)}{P(accepted)}\\[/tex]

                                [tex]=\frac{\frac{57}{1275}}{\frac{170}{1275}} \\\\= \frac{57}{1275} \times \frac{1275}{170} \\\\= \frac{57}{170} \\\\= 0.3352941\approx 33.52%[/tex]
