This question needs an explanation of how much flour is needed to make a cake.

Based on the amount of Nacho cheese corn chips and the calories per gram, the calories per party bag is 1,094.6 calories

First, convert ounces to grams:

= 1 ounce is 28.3495 grams

Party bag in grams:

= 15 x 28.3495

= 425.243 grams

The amount of calories is:

= 425.243 x 28.6% x 9

= 1,094.6 calories

Answer:

y=4x-2

you can find the y intercept if you plot a confirmed point on a graph and follow the slope to the line.

Answer:

y = 4x - 2

Step-by-step explanation:

Since we are given the slope already, we can solve for the y-intercept using the slope, the given point, and the formula [ y = mx + b ]

y = 4x + b

2 = 4(1) + b

2 = 4 + b

-2 = b

Substitute with what we solved for into the formula.

y = 4x - 2

Answer:

(0, 2) is a solution

Step-by-step explanation:

The Solution of an Equation

Given the equation

-2x + y = -1

An ordered pair (a,b) is a solution of the equation if

-2a + b = -1

Let's test the point (0,2) to check if it's a solution of the equation:

Replacing x=0, y=-1

-2(0) + (-1) = -1

0 - 1 = -1

-1 = -1

Since the equation is satisfied, the pair (0,2) is a solution.

Answer: O Yes, (0, 2) is a solution

The probability that the sample mean would be less than 132.25 liters is 0.0558.

The central limit theorem (CLT) of probability theory states that, under the assumption that all samples are of equal size and regardless of the population's actual distribution shape. The distribution of a sample variable approaches a normal distribution (i.e., a "bell curve") as the sample size increases.

Given, \(\mu\) = 138 , \(\sigma\)= 28

According to the central limit theorem,

P(\(\bar{x }\) < x) = P( Z < x - \(\mu\) / \(\sigma\) / \(\sqrt{n}\) )

So,

P( \(\bar{x }\)< 132.25 ) = P( Z < 132.25 - 138 / 28 / \(\sqrt{60}\) )

= P( Z < -1.5907)

= 1 - P( Z < 1.5907)

= 1 - 0.9442

= 0.0558

This option does not match the given integral expression, so it is incorrect.

b. ∫∫∫ √(16 - z^2) dz dr de

This option matches the given integral expression, so it is a possible choice.

c. ∫∫∫ 1 dz dr de

This option does not match the given integral expression, so it is incorrect.

d. ∫∫∫ r dz dr de

This option does not match the given integral expression, so it is incorrect.

e. None of the above

A. In the alternate universe, the p subshell would have 5 orbitals.

B. In the alternate universe, the d subshell would have 10 orbitals.

In the alternate universe where the possible values of mℓ range from -l-1 to l+1, the number of orbitals in each subshell can be determined.

A. For the p subshell, the value of l is 1. Therefore, the range of mℓ would be -1, 0, and 1. Including the additional values of -2 and 2 from the alternate universe, the total number of orbitals in the p subshell would be 5 (mℓ = -2, -1, 0, 1, 2).

B. For the d subshell, the value of l is 2. In the conventional universe, the range of mℓ would be -2, -1, 0, 1, and 2, resulting in 5 orbitals. However, in the alternate universe, the range would extend to -3 and 3. Including these additional values, the total number of orbitals in the d subshell would be 10 (mℓ = -3, -2, -1, 0, 1, 2, 3).

Therefore, in the alternate universe, the p subshell would have 5 orbitals, and the d subshell would have 10 orbitals.

It will take 5.78 years to earn an extra $100,000 regardless of which option you choose. if we double the amount then it will take approx 10 year.

The high-yield account with continuous compounding interest is a safer investment since it won't be at risk of losing money in a business venture.

Since High-yield account offering 12% continuous interest.

\(A = Pe^{rt}\)

Where A is the final amount, P is the principal amount, r is the annual interest rate, t is the time in years, and e is Euler's number, approximately equal to 2.71828.

we can plug in the given values to find out how long it will take to earn an extra $100,000:

\((P + $500,000)e^{0.12t} - P = $100,000\)

t = ln[(P + $500,000 + $100,000)/P] / 0.12,

where P = $500,000

Substituting the values,

t = ln[(500,000 + 500,000 + 100,000)/500,000] / 0.12t

= ln(2.2)/0.12t = 5.78 years (approx.)

Now we can plug in the given values to find out how long it will take to earn an extra $100,000:

\((P + $500,000)(1 + 0.12/4)^{4t} - P = $100,000\)

t = [ln(P + $600,000) - ln(P)] / [4 ln(1.03)]

where P = $500,000

Substituting the values, we get:

t = [ln(1,100,000) - ln(500,000)] / [4 ln(1.03)]t = 5.78 years (approx.)

After comparing both investment options, it will take approximately 5.78 years to earn an extra $100,000 regardless of which option you choose. However, the high-yield account with continuous compounding interest is a safer investment since you won't be at risk of losing money in a business venture.

Therefore, the simplified sum of the expression 7 1/4 and 4 5/12 is 35/3 that is option D, 11 2/3.

In mathematics, an expression is a combination of symbols and/or numbers that represents a quantity or a mathematical relationship between quantities. Expressions can be simple or complex, and can involve arithmetic operations, algebraic operations, functions, and variables.

Here,

To add these mixed numbers, we need to first convert them to improper fractions with the same denominator:

7 1/4 = 28/4 + 1/4

= 29/4

4 5/12 = 48/12 + 5/12

= 53/12

Now, we can add the fractions:

=29/4 + 53/12

To find a common denominator, we can multiply the denominator of the first fraction by 3 and the denominator of the second fraction by 1:

29/4 × 3/3 = 87/12

53/12 × 1/1 = 53/12

Now we have the same denominator, so we can add the numerators:

87/12 + 53/12 = 140/12

We can simplify by dividing the numerator and denominator by their greatest common factor, which is 4:

140/12 ÷ 4/4 = 35/3

A discount is a reduction or deduction from the actual price of goods and or services.

The cost of the cell phone = $600

The percentage discount on the of the cell phone = 25%

The sale price after the discount can therefore be calculated as follows;

Answer:

Step-by-step explanation:

To express the confidence interval 0.039 < p < 0.479 in the form p ± E, we need to find the midpoint of the interval and half of the width.

The midpoint of the interval is the average of the lower and upper bounds:

Midpoint = (0.039 + 0.479) / 2 = 0.259

The width of the interval is the difference between the upper and lower bounds:

Width = 0.479 - 0.039 = 0.44

Half of the width is obtained by dividing the width by 2:

Half Width = 0.44 / 2 = 0.22

Therefore, the confidence interval 0.039 < p < 0.479 can be expressed as:

p ± E = 0.259 ± 0.22

So, the correct option is:

D. 0.259 ± 0.22

Answer:

he right .75

Step-by-step explanation:

The relative rate of population change after seven years from now is a) 1.7 % (rounded off to 1 decimal place) b) Yes, the relative rate of population change will reach 2.3% in 19.21 years

The function for population t years from now is P(t)= 2+ 1.2e^(0.04t)

a) relative rate of change of population

= P'(t) / P(t)

= (0+1.2e^(0.04t) * 0.04 )/ ( 2+ 1.2e^(.04t) )

= 0.048 e ^(0.04t) / (2 + 1.2e^(0.04t) )

Relative rate of change of population 7 years from now

= 0.048 e ^(0.04 * 7) / (2+ 1.2e^(0.04*7))

=0.0177 = 0.177 * 100 = 1.7 % per year (rounded off to one decimal place

b) For the relative rate of change to reach 2.3 %

P'(t) / P(t) = 2.3 % = 0.023

⇒(0+1.2e^(0.04t) * 0.04 )/ ( 2+ 1.2e^(0.04t) ) = 0.023

⇒0.048e ^(0.04t) = 0.046 + 0.0267e^(0.04t)

⇒e ^(0.04t) = 0.958 + 0.556e ^(0.04t)

⇒e ^(0.04t) ( 1 - 0.556) = 0.958

⇒e ^(0.04t) ( 0.444) = 0.958

⇒e ^(0.04t) = 2.157

⇒0.04t = ln(2.157)           (applying ln on both sides)

⇒t = 19.21 years

The relative rate of population change is 2.3% in 19.21 years

Step-by-step explanation:

The total ratio between Paul and Malachy is 2 + 3 = 5.

The second ratio is between Paul, his wife and their son in the ratio 5:4:1. The total ratio between Paul, his wife and their son is:

5 + 4 + 1 = 10

The amount that Paul's wife will receive is:

4/10 * 1100 = £440

The amount that their son will receive is:
