Which point on the number line represents 7 less than 4? How do you know?

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:

0.23

Step-by-step explanation:

Given the data:

____(x) __(y)__(x - m1) /s1 ___(y-m2) /s2

1 ___6 ___8__ - 0.2 _______0.625

2 __5 ___ 5__ - 0.7________ - 1.25

3 __9____6__ 1.3 ________ - 0.625

4__ 4____ 7__ - 1.2 ______ 0

5__ 8 ____9 _ 0.8 _______ 1.25

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)

= 0.234

= 0.23

Answer:

The figure is rotated 180 degrees. Also we don't use "compasses" in math.

Step-by-step explanation:

This question is incomplete, the complete question is;

The manager of Lawn and Garden Services would like to estimate the proportion of her employees' time spent performing various gardening and lawn care activities. She has made 400 random observations of a typical worker, with the following results:

Activity                                        Time Observed

Mowing                                          200

Trimming                                       80

Raking                                           40

Miscellaneous                               80

What is the probability that the true proportion of time spent mowing is exactly equal to the sample proportio;

Multiple Choice

a) 1

b) 0

c) 5

d) 2

e) 1

Answer:

b) 0

Step-by-step explanation:

Given that;

Activity            Time Observed

Mowing             200

Trimming           80

Ranking             40

Miscellaneous   80

Total                 400

Now since proportion of time spent on mowing will be

200 / 400 = 0.5

there will be no chance that the true proportion of time spent mowing is exactly equal to the sample proportion.

Where true proportion is 200 and sample is 400

So the probability is 0.

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

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]

well the answer is 90 degress  but it also adds up to 360 degress

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:

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:

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

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:

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.
