She received 1 package from SendQuick Package Service, 2 packages from Ralph's Express and 8 packages from Speedy Delivery

A word problem is a mathematical exercise which is in the form of a hypothetical question that needs mathematical analysis and equations to be solved.

Let SQPS represent SendQuick Package Service

SD represent Speedy Delivery

RE represent Ralph's Express, then:

Let the number of packages from SQPS be x

The number of packages from RE will be x+1

The number of packages from SD will be 4(x+1)

Given that the total number of packages received is 11, then:

x + x+1 + 4(x+1) = 11

x + x+1 + 4x + 4 = 11

6x + 5 = 11

6x = 11-5

6x = 6

x = 1

x = 1 package from SQPS

x + 1 = 2 packages from RE

4(x+1) = 8 packages from SD

Therefore, Erica Franz received 1 package from SendQuick Package Service, 2 packages from Ralph's Express and 8 packages from Speedy Delivery

Answer:

Step-by-step explanation:

In this question we have given an equation that is 3 ( q - 7 ) = 27 and we have asked to solve this equation that means to find the value of q .

Solution : -

\( \quad \: \longmapsto \: 3(q - 7) = 27\)

Step 1 : Solving parenthesis :

\(\quad \: \longmapsto \:3q - 21 = 27\)

Step 2 : Adding 21 on both sides :

\(\quad \: \longmapsto \:3q - \cancel{ 21} + \cancel{21} = 27 + 21\)

On further calculations we get :

\(\quad \: \longmapsto \:3q = 48\)

Step 3 : Dividing by 3 from both sides :

\(\quad \: \longmapsto \: \frac{ \cancel{3}q}{ \cancel{3}} = \cancel {\frac{48}{3} }\)

On further calculations we get :

\(\quad \: \longmapsto \: \pink{\boxed{\frak{q = 16}}}\)

Verifying : -

Now we are very our answer by substituting value of q in the given equation . So ,

Therefore, our solution is correct .

Answer:

\( \: \)

Step-by-step explanation:

So here, a equation is given and we are asked to solve the equation.

\( \\ \dashrightarrow \sf \qquad3(q-7)=27 \\ \\ \)

For this, we have to use the Distributive property, which is :

\(\\ \dashrightarrow \sf \qquad3q-21=27 \\ \\ \)

Transposing the constant term (-21) to the right side we get :

\(\\ \dashrightarrow \sf \qquad3q=27 + 21 \\ \\ \)

Adding the like terms :

\( \\ \dashrightarrow \sf \qquad3q=48 \\ \\ \)

Now, We'll divide both sides by 3 :

\( \\ \dashrightarrow \sf \qquad \frac{3q}{3} = \frac{48}{3} \\ \\ \)

\(\dashrightarrow \bf \qquad \: q=16 \\ \\ \)

S = 626 yd².

The surface area of a rectangular prism of height h, width w and length l is given by:

S = 2(hw + lw + lh).

This means that the area of each rectangular face of the prism is calculated, and then the surface area is given by the sum of all these areas.

For this problem, we have two prisms, with the dimensions given as follows:

Hence the combined surface area is given as follows:

S = 2 x (4 x 4 + 4 x 12 + 4 x 12) + 2 x (12 x 11 + 12 x 3 + 11 x 3)

Answer:

Step-by-step explanation:

The area of the window is 49 10/12 square feet, which can be simplified to 49 5/6 square feet. The answer is (B) 49 5/6 ft2.

The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.

The width of the window is 8 2/3 feet and the height is 5 3/4 feet. To find the area, we can simply multiply these two values:

Area = width × height

Area = (8 2/3 feet) × (5 3/4 feet)

First, we need to convert the mixed numbers to improper fractions:

8 2/3 = (8 × 3 + 2)/3 = 26/3

5 3/4 = (5 × 4 + 3)/4 = 23/4

Now, we can multiply the fractions:

Area = (26/3 feet) × (23/4 feet)

Area = (26 × 23)/(3 × 4) square feet

Area = 598/12 square feet

To simplify the mixed number, we can divide the numerator by the denominator:

598 ÷ 12 = 49 10/12

Therefore, the area of the window is 49 10/12 square feet, which can be simplified to 49 5/6 square feet. The answer is (B) 49 5/6 ft2.

Answer:

x=2.3

Step-by-step explanation:

Isosceles triangle means both sides are the same length, triangle is also right meaning you can plug values into Pythagorean theorem (\(a^2+b^2=c^2\))

\(x^2+x^2=\sqrt{11}^2 \\2x^2=11\\x=\sqrt{\frac{11}{2} } \\x=2.345...\\x=2.3\)

Assuming all my math is right, this is your answer

The function that models the above behavior is given as:

f(x) = ACos(B(x + C)) + 6 ..... .......i

where x = 1 (that is January)

D (Average Snowfall) = 6.

Hence, the amplitude (A) is given as:
A = 6-1

= 5

A mathematical function is a function comprising of different variables that    represent different factors or events and the relationships between them.

Recall that in a year we have 12 months. Hence, P = 12

→ P = (2π) /.B → (2π)/B = 12 → B = π/6

Taking the values of A and B and plugging them in, we ahve:

F(x) = 5 cos (π/6(x + C)) + 6................ii

This means that in July, we'll have

x = 7 and f(x) = 1

Therefore,

1 = 5cos ((π/6) (7 + C) + 6 → 5 Cos  ((π/6) (7 + C) →  -5cos ((π/6) (7 + C)

= -1

→   ((π/6) (7 + C) = π

→ 7 + C = 6

→ C = -1

Taking equation ii, we have

F(x) = 5cos ((π6) (x -1)) + 6

F (x) > 10

Therefore

5cos ((π/6) (x-1) + 6 > 10

→  cos ((π/6) (x-1) + 6 > 4/5

→  (π/6) (x-1)  > Cos⁻¹ (4/5)

(π/6) (x-1)  < 0.6435 and

(π/6) (x-1)  > 5.6397

→ x < 2.23 and x > 11.77

The interpretation is that upwards of ten inches of snow fall in January, February, November, and December.

Answer:

B 1/4

Step-by-step explanation:

f(x) = y = x⁴ + 5

the inverse function is

y - 5 = x⁴

x = 4th root(y - 5)

now we rename y and x to make it a regular function definition :

g(x) = y = ±4th root(x - 5) = ±(x - 5)^(1/4)

because g(6) = 1 (positive), we have

g(x) = (x - 5)^(1/4)

and since we are using the positive branch, it means also that all the tangent slopes (= g'(x)) are positive.

g'(x) = 1/4 × (x - 5)^(-3/4) × 1 = 1/4 × (x - 5)^(-3/4)

because (x - 5)' = 1

g'(6) = 1/4 × (6 - 5)^(-3/4) = 1/4 × (1/1³)^(1/4) =

= 1/4 × 1^(1/4) = 1/4 × 1 = 1/4

please note, we are using only the positive root result in this case to get a positive result as tangent slope for g(x) as enforced by g(6) = 1.

Answer:

When we say that an allele is "fixed," it means that a particular allele has reached a frequency of 100% in a population.

Step-by-step explanation:

Alleles are different forms of a gene that occupy the same position on homologous chromosomes. In a population, different alleles can exist for a specific gene. However, through various evolutionary processes such as natural selection, genetic drift, or gene flow, one allele may become predominant and eventually fixate within the population.

The fixation of an allele can occur through different mechanisms. For example, if a beneficial allele provides a selective advantage to individuals carrying it, it is more likely to increase in frequency and eventually become fixed in the population. On the other hand, genetic drift, which is the random change in allele frequencies due to chance events, can also lead to the fixation of an allele, especially in small populations.

Once an allele is fixed in a population, it means that all future generations will inherit that allele, and no alternative alleles will be present at that particular gene locus.

The probability of producing less than 239,000 barrels is 0.8413.

The probability of producing less than 239,000 barrels can be found using the z-score formula. The z-score formula is given by:
z = (x - μ) / σ
Where x is the value we are interested in, μ is the mean, and σ is the standard deviation.
Plugging in the given values, we get:
z = (239,000 - 232,000) / 7,000
z = 1
Now, we can use the standard normal table to find the probability of producing less than 239,000 barrels. The standard normal table gives the probability of a value being less than a given z-score. For a z-score of 1, the probability is 0.8413.

Step-by-step explanation:

The correct answer is option c. 95%. Reaching out two standard errors on either side of the sample proportion gives us an interval of 95% confidence.

This is due to the fact that two standard errors on either side of the sample proportion will cover around 95% of the population's cases.

We can typically determine the true proportion in the population using this range of two standard errors on either side of the sample proportion.

This is because it helps us identify any potential outliers in the population and provides a range of population proportions for which we may be 95% certain.

We are 95% certain that the true percentage is capable inside the interval if we stretch out two standard errors on either side of the sample proportion.
