Answer: c

Step-by-step explanation: it is the answer i think (Jesus love you he is coming back)

The number line (d) represents the values of x that makes -3x + 1 < 7 to be true

The inequality is given as:

-3x + 1 < 7

Subtract 1 from both sides

-3x < 6

Divide both sides by -3

x > -2

This means that the number line must show an inequality that is greater than -2

From the list of options, the number line that represents x > -2 is (d)

Hence, the number line (d) represents the values of x that makes -3x + 1 < 7 to be true

The function is an exponential growth function

The function is given as

y=2(1.06)^9

We can begin by rewriting the given equation as:

y = 2 * 1.06t

So, we have

y = 2 * (1 + 0.06)^t

Now we can see that the equation is in the form y = a*b^t,

where a = 2 and b = 1.06^9

This equation represents exponential growth because the base of the exponent, b = 1.06, is greater than 1.

We can re-write it in the form y = a(1+r)t,

we can find the value of r by subtracting 1 from 1.06 which is 0.06 and the value of a is 2.

so we have y = 2(1+0.06)^t

So, the equation represents exponential growth with a = 2 and r = 0.06

Step-by-step explanation:

Answer:

Step-by-step explanation:

because 5(k-78)=40 okay so you divide 5 both sides so 5/5 and 40/5 so 5 disappears and you get an 8 so this should be the equation now : k -78 =8 . so now you move the constant to the right so it looks like this : k =8+78 . so now you just add that and it gives you 86 . K =86

Call the amount of apples Fatima bought as x.

She gave half of the apple to Salma -> x : 2

Then she gave Maha 5 apples -> x : 2 - 5

She is left with 3 apples, so we have the equation x : 2 - 5 = 3

Solve for x :
x = (3+5) x 2 = 16.

Fatima bought 16 number of apples from the grocery store.

Two or more expressions with an Equal sign is called as Equation.

Let  the number of apples Fatima bought will be "x".

Fatima gave half of the apples to Salma, which is (1/2)x apples.

So, she had (1/2)x apples left.

Then she gave 5 apples to Maha, which means she had (1/2)x - 5 apples left.

Finally, she kept 3 apples for herself, which means she had (1/2)x - 5 - 3 apples left.

We know that the number of apples she had left is equal to the number of apples she gave away

(1/2)x - 5 - 3 = (1/2)x

Solve for x

-8 = -x/2

Multiplying both sides by -2, we get:

x = 16

Hence, Fatima bought 16 apples.

The logically equivalent statement to p → q is:

~q → ~p

The conditional statement:

p → q

Assuming p and q are propositions, the conditional statement may be expressed as:

"If p holds true, then q follows suit. "

'

Whenever p is true, q is true as well. This implies that if q is false, then p must also be false.

We can rephrase this statement cleverly using the negative propositions, which include the opposite or contradictory statements.

~p  and ~q

These mean:

Not p and Not q respectively.

Then the statement:

Answer:

At a package weight of 8 kilograms, the two couriers both cost $37

Step-by-step explanation:

Let's say the package weighs w kg.

First courier: 13 + 3 per kg = 13 + 3 for each w = 13 + 3w

Second courier: 5 + 4w

They are equal in cost, so

13 + 3w = 5 + 4w

subtract 3w from both sides to put all the variables on one isde

13 = 5 + w

subtract 8 from both sides to solve for w

w = 8

plug w=8 into one side of the original equation to solve for cost

13 + 3w = 5 + 4w = 37

The height of the cone is 24 meters.

Option A is the correct answer.

It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.

We have,

The formula for the volume of a cone.

V = (1/3)πr²h

Where r is the radius of the base and h is the height.

The diameter of the cone = 12 m.

So,

The radius is half of the diameter:

r = 12/2

r = 6 m

Now,

The volume of the cone is 904 m³.

Substituting the known values into the formula.

904  = (1/3) × 3.14 × 6 x 6 × h

Simplifying the equation.

904 = 37.68 h

Dividing both sides by 37.68.

h = 23.99

h = 24

Therefore,

The height of the cone is 24 meters.

To linearize the function cos^5(x), we can use the following identity:

cos^5(x) = (cos^2(x))^2 * cos(x) = (1 - sin^2(x))^2 * cos(x)

Now, we can use the identity e^(ix) = cos(x) + i sin(x) to rewrite the expression as follows:

(1 - sin^2(x))^2 * cos(x) = ((1 - e^(ix) * e^(-ix))/2)^2 * (e^(ix) + e^(-ix))/2

= (1/16) * (e^(4ix) - 4e^(2ix) + 6 - 4e^(-2ix) + e^(-4ix))

This expression is now linear in terms of e^(ix) and e^(-ix). Therefore, we have linearized the function cos^5(x) as:

(1/16) * (e^(4ix) - 4e^(2ix) + 6 - 4e^(-2ix) + e^(-4ix))

After 300 trials, the experimental probabilities may not align perfectly with the theoretical probabilities. However, with more trials, the experimental probabilities tend to converge towards the theoretical probabilities for closer alignment.

To examine whether experimental probabilities after 300 trials align closely with theoretical probabilities, let's consider an example of flipping a fair coin.

Theoretical probability: When flipping a fair coin, the theoretical probability of obtaining heads or tails is 0.5 each. This assumes that the coin is unbiased and has an equal chance of landing on either side.

Experimental probability: After conducting 300 trials of flipping the coin, we record the outcomes and calculate the experimental probabilities. Let's assume that heads occurred 160 times and tails occurred 140 times.

Experimental probability of heads: 160/300 = 0.5333

Experimental probability of tails: 140/300 = 0.4667

Comparing the experimental probabilities to the theoretical probabilities, we can observe that the experimental probability of heads is slightly higher than the theoretical probability, while the experimental probability of tails is slightly lower.

In this particular example, the experimental probabilities after 300 trials do not align perfectly with the theoretical probabilities. However, it is important to note that these differences can be attributed to sampling variability, as the experimental outcomes are subject to random fluctuations.

To draw a more definitive conclusion about the alignment between experimental and theoretical probabilities, a larger number of trials would need to be conducted. As the number of trials increases, the experimental probabilities tend to converge towards the theoretical probabilities, providing a closer alignment between the two.

The number of people in the set C ∩ D (customers who purchased both cats and dogs) is obtained by adding the overlap of D and C (3) with the overlap of all 3 circles (1), resulting in a total of 4 individuals.

The correct answer is 4.

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to analyze the overlapping regions in the Venn diagram.

Given information:

- Circle C (cats): 15

- Circle D (dogs): 21

- Circle F (fish): 12

- Overlap of C and F: 2

- Overlap of F and D: 0

- Overlap of D and C: 3

- Overlap of all 3 circles: 1

- Number outside of circles: 14

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to consider the overlapping region between circles C and D.

From the information given, we know that the overlap of D and C is 3. Additionally, we have the overlap of all 3 circles, which is 1. The overlap of all 3 circles includes the region where customers have purchased cats, dogs, and fish.

To calculate the number of people in the set C ∩ D, we add the overlap of D and C (3) to the overlap of all 3 circles (1). This gives us 3 + 1 = 4.

Therefore, from the options given correct one is 4.
