Many children develop the ability to do simple arithmetic problems during their early childhood years, typically between the ages of 4 and 6. Correct option is a).

During this time, children start to understand basic mathematical concepts such as counting, addition, and subtraction. They may also begin to recognize and name numbers and use basic math vocabulary. However, it's important to note that every child develops at their own pace and some may show these skills earlier or later than others. It's also important for parents and caregivers to provide opportunities for children to practice and reinforce these skills through activities such as counting objects, playing number games, and solving simple math problems.

Answer:

x = 6 , y = 30 , z = 66

Step-by-step explanation:

• All 4 sides of a rhombus are congruent

given one side is 59 , then all 4 sides equal 59

10x - 1 = 59 ( add 1 to both sides )

10x = 60 ( divide both sides by 10 )

x = 6

-------------------

2y - 1 = 59 ( add 1 to both sides )

2y = 60 ( divide both sides by 2 )

y = 30

--------------------

z - 7 = 59 ( add 7 to both sides )

z = 66

Michael will save $0.50 for every 6 yogurt cups, which means he will save $0.0833 on every yogurt cup purchased ($0.50/6).

If Michael buys 12 yogurt cups, he can apply the coupon twice and save $1.00 in total.

The cost of 12 yogurt cups is:

$6.60 ($0.55/cup x 12 cups).

The total cost of all the items he purchased is:

$6.60 (yogurt cups) + $3.59 (milk) + $2.75 (orange juice) + $11.97 (Tide) + $4.35 (Downy) - $0.85 (Downy coupon) = $28.41

After applying the coupon for the yogurt cups, the total cost is reduced by $1.00 to $27.41.

If researchers report that the results from their study were significant, p < .05, this means that we would expect the results to occur by chance less than 5 times out of 100.

When researchers report that the results from their study were significant, p < .05, it means that we would expect the results to occur by chance less than 5 times out of 100. This threshold is commonly used in statistical hypothesis testing.

In statistical hypothesis testing, the p-value represents the probability of obtaining results as extreme as the observed results, assuming that the null hypothesis is true. If the p-value is less than the predetermined significance level of .05 (or 5%), it is considered statistically significant. This means that the observed results are unlikely to have occurred by chance alone, and there is evidence to support the alternative hypothesis.

Therefore, option D, "We would expect the results to occur by chance less than 5 times out of 100," is the correct interpretation of reporting significant results with p < .05.

The solution for the system of equations 2x - 3y = 50 and 7x + 8y = -10 by elimination are x = 10, y = -10

we shall write the equations as:

2x - 3y = 50...(1)

7x + 8y = -10...(2)

multiply equation (1) by 7 to get equation (3) and equation (2) by 2 to get equation (4)

7(2x - 3y) = 7 × 50

14x - 21y = 350...(3)

2(7x + 8y) = 2 × -10

14x + 16y = -20...(4)

subtract equation (3) from (4) to eliminate x

14x + 16y - 14x + 21y = -20 - 350

37y = -370

divide through by 37

y = -10

put the value -10 for y in equation (1) to get x

2x - 3(-10) = 50

2x + 30 = 50

2x = 50 - 30 {subtract 30 from both sides}

2x = 20

x = 20/2 {divide through by 2}

x = 10

Therefore, the solution for the system of equations 2x - 3y = 50 and 7x + 8y = -10 by elimination are x = 10, y = -10

Question 9

The point (30,15) means that x = 30 and y = 15 pair up together.

Similarly, (40,25) means we have x = 40 and y = 25 paired up.

Apply the slope formula to get

m = (y2-y1)/(x2-x1)

m = (25-15)/(40-30)

m = 10/10

m = 1

The slope is 1.

It tells us that each time y goes up by 1, x is also increasing by 1.

slope = rise/run = 1/1

rise = 1, run = 1

The rise is the change in y, the run is the change in x.

This means the plant's height (y) goes up by 1 cm each time the number of days (x) goes up by 1.

In short, the plant's height is increasing by 1 cm per day

Question 10

y varies directly with x, so y = kx for some constant k.

We're then told that x = -1 and y = -2 pair up together.

Let's find k based on those items

y = kx

y/x = k

k = y/x

k = -2/(-1)

k = 2

So y = kx becomes y = 2x

Then we're asked to find x when y = -4

y = 2x

y/2 = x

x = y/2

x = -4/2

x = -2

We have to find the value of x for the given equation e^(−x^)−e^x =3. Here we can use a small trick to get the solution. We know that e^-x is the reciprocal of e^x. So we can replace e^-x with 1/e^x. Now we have the equation e^(−x^)−e^x =3 in the form e^x - 1/e^x = 3.

This is a quadratic equation in the form ax^2 + bx + c = 0. Here a = 1, b = 0, c = -3. We can solve this quadratic equation to get the value of x.

Given equation is e^(−x^)−e^x =3.We can replace e^-x with 1/e^x.Now the equation is e^(x) - 1/e^(x) = 3.

Let's take e^x as a variable and solve the equation:e^x - 1/e^x = 3Multiplying both sides by e^x, we get e^x * e^x - 1 = 3e^xNow e^(2x) - 3e^x - 1 = 0.

This is a quadratic equation in the form ax^2 + bx + c = 0. Here a = 1, b = -3, c = -1.

We can solve this quadratic equation using the quadratic formula which is given as:x = [-b ± sqrt(b^2-4ac)]/2a.

Substituting the values, we get:x = [-(-3) ± sqrt((-3)^2-4(1)(-1))]/2(1)x = [3 ± sqrt(13)]/2Hence the value of x is x = [3 ± sqrt(13)]/2.

Hence, the lengths of the pairs of corresponding sides or corresponding side lengths are proportional to one another when two (2) geometric figures are similar.

Like terms are those which have the same base

\( \mapsto{ \text{32 = 2(6 + 2w) }}\)

\( \text{Step \: 2 \: : Distribute \: 2 \: through \: the \: parentheses}\)

\( \mapsto{ \text{32 = 12 + 4w}}\)

\( \text{Step \: 3 \: : Swap \: the \: sides \: of \: the \: equation}\)

\( \text{Step \: 4 \: : Move \: 12 \: to \: right \: hand \: side \: and \: change \: its \: sign}\)

\( \mapsto{ \text{4w = 32 - 12}}\)

\( \mapsto{ \sf{4w = 20}}\)

\( \text{Step \: 6 \: : Divide \: both \: sides \: by \: 4}\)

\( \mapsto{ \sf{ \frac{4w}{4} = \frac{20}{4}}}\)

Since y_1(0) = 1, it satisfies the initial condition. However, y_2(0) = 0 does not satisfy the initial condition, as it should be y(0) = 1. Therefore, only y_1(t) is a solution of the initial value problem.

To verify that both y_1(t) = 1 - t and y_2(t) = -t^2/4 are solutions of the initial value problem, we first need to understand what the problem is. An initial value problem is a differential equation that includes an initial condition. In this case, we can assume that the initial condition is y(0) = 1.
Now, let's substitute both y_1(t) and y_2(t) into the differential equation and see if they satisfy the initial condition. The differential equation is not provided, but assuming it is y'(t) = -t/2, we have:
y_1'(t) = -1
y_2'(t) = -t/2
Substituting y_1(t) and y_2(t) into the differential equation gives:
y_1'(t) = -1

= -t/2 (when t = 2)
y_2'(t) = -t/2

= -t/2 (for all t)
Thus, both y_1(t) and y_2(t) satisfy the differential equation. Now, let's check if they satisfy the initial condition.
y_1(0) = 1 - 0

= 1
y_2(0) = -0^2/4

= 0
In conclusion, y_1(t) = 1 - t is the only solution that satisfies the differential equation and initial condition, while y_2(t) = -t^2/4 is not a solution since it does not satisfy the initial condition.

Step-by-step explanation:

Trust me

The probability of obtaining a value between two points will always be a positive value between 0 and 1.

If the measurements of a quantity are governed by the Gaussian distribution function (also known as the normal distribution), we can calculate the probability of obtaining a value between two specified points using the cumulative distribution function (CDF) of the normal distribution.

The CDF of the Gaussian distribution represents the probability that a random variable takes on a value less than or equal to a given point. To find the probability of obtaining a value between two points, we can subtract the CDF values corresponding to the lower and upper bounds.

Mathematically, the probability of obtaining a value between a lower bound (let's call it 'a') and an upper bound (let's call it 'b') can be calculated as follow

P(a < x < b) = Φ(b) - Φ(a)

Here, Φ represents the CDF of the Gaussian distribution.

To calculate this probability, we need to know the mean (μ) and standard deviation (σ) of the Gaussian distribution. These parameters define the shape and characteristics of the distribution.

Given the mean (μ) and standard deviation (σ), we can use statistical software, tables, or programming languages to find the values of Φ(b) and Φ(a) and then subtract them to obtain the probability.

It's important to note that the Gaussian distribution is symmetric, and the total area under the curve is equal to 1.
