Help?? What decimal place value is .7 in

Answer:

Increase by 10% of students that bought lunch.

Step-by-step explanation:

I think the percent change was by 10%. Because 10% of those students who packed lunched on Monday did not pack lunch on Tuesday, and assuming that they either buy or pack it that means that 10% more students bought lunch.

Answer:

3.8731

Step-by-step explanation:

The standard deviation of the sampling distribution of the sample​ mean is also called the standard error of the mean expressed as;

SM = s/√n

s is the standard deviation of the random variable X

n is the sample size

Given

s = 15

n = 15

Required

Standard deviation of the sampling distribution of the sample​ mean.

Substituting the given parameters into the expression above;

SM = 15/√15

SM = 15/3.8729

SM = 3.8731

Hence the standard deviation of the sampling distribution of the sample​ mean is 3.8731

A) congruent triangles

Step-by-step explanation:

When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.

Answer:

Option (D)

Step-by-step explanation:

Equation to represent the household expenditure per week will be in the form of,

y = mx + b

Where m = slope of the line

b = y-intercept

From the graph attached,

Since, line of best fit touches the positive side of the y-axis, y-intercept will be positive.

Since, y-values on the graph are decreasing with the increase in the x-values,

Slope of the graph will be negative.

[Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex], Since rise of the line is negative and run is positive, slope will be negative]

By these properties equation of the linear graph will be,

y = -0.34x + 5.19

Option (D) will be the correct option.

The equation that best models this data set is y = -0.34x + 5.19

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the time spent on chores for x household members.

From the graph, the line passes through (3, 4.25) and (8, 2.5). Hence:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-4.25=\frac{2.5-4.25}{8-3}(x-3) \\\\y-4.25=-0.35(x-3)\\\\y=-0.34x+5.2[/tex]

The equation that best models this data set is y = -0.34x + 5.19

Answer:

[tex]Profit = \$120[/tex]

Step-by-step explanation:

Given

[tex]Cost\ Price = \$7[/tex] per dozen

[tex]Selling\ Price = \$1.25[/tex]

Required

Determine the profit on 15 dozen

First, we need to determine the selling price of 1 dozen.

[tex]Selling\ Price = \$1.25 * 12[/tex]

[tex]Selling\ Price = \$15[/tex]

Next, we calculate the profit on a dozen

[tex]Profit = Selling\ Price - Cost\ Price[/tex]

[tex]Profit = \$15 - \$7[/tex]

[tex]Profit = \$8[/tex]

Profit on 15 dozen is:

[tex]Profit = 15 * \$8[/tex]

[tex]Profit = \$120[/tex]

Answer:

The smaller number is 5.

The bigger number is 15.

Step-by-step explanation:

Let the smaller number be x and the bigger number be x+10.

x+x+10 = 4x

2x+10 = 4x

10 = 4x-2x

2x = 10

x = 10÷2

  = 5

x+10 = 5+10

       = 15

Answer:

La probabilidad de que el estudiante entre, es 0.7

Entonces la probabilidad de que el estudiante no entre, es 1 - 0.7 = 0.3.

Ahora, si de 5 estudiantes, 3 entran y 2 no, entonces la probabilidad para un dado arreglo es: 0.7 tres veces, y 0.3 dos veces.

Y la probabilidad conjunta es igual al producto de las probabilidades individuales.

P = (0.7^3)(0.3^2)

Pero esto es para un arreglo, tenemos que tener en cuenta las permutaciones.

Sabemos que para M elementos, el numero de diferentes arreglos de N elementos (tal que N ≤ M) es:

[tex]C(M, N) = \frac{M!}{(M - N)!*N!}[/tex]

En este caso, tenemos que M = 5 y N = 3, entonces tenemos:

[tex]C(5, 3) = \frac{5!}{2!*3!} = 5*4/2 = 10[/tex]

Entonces la probabilidad va a ser:

P = 10* (0.7^3)(0.3^2) = 0.3087

Answer: There would be $4590 (approx.) in the account after 8 years.

Step-by-step explanation:

Formula to calculate accumulated amount if compounded monthly :

[tex]A= P(1+\dfrac{r}{12\times100})^{12t}[/tex], where P+ principal value, r = rate of interest , t = time.

Given: P=$2,800 , r = 6.2%

t= 8 years

Substitute all values in the formula , we get

[tex]A=2800(1+\dfrac{6.2}{1200})^{12\times8}\\\\=2800(1+0.005167)^{96}\\\\=2800(1.005167)^{96}\\\\=2800(1.64009619996)=4592.2693\approx4590\text{ [Rounded to the nearest ten dollars] }[/tex]

Hence, There would be $4590 (approx.) in the account after 8 years.

b. ✓8x²y. 2. 2y✓2x

c. ✓4x²y. 3. 2xy²

d. ✓16xy². 4. 2x✓2y

e. ✓8xy². 5. 4y✓x

a. ✓4x²y^4 = ✓4 × ✓x² × ✓y^4

= 2 × x × y²

= 2xy²

Therefore, ✓4x²y^4 = 2xy²

b. ✓8x²y = ✓8 × ✓x² × ✓y

= ✓4 × ✓2 × ✓x² × ✓y

= 2 × ✓2 × x × ✓y

= 2x✓2y

Therefore, ✓8x²y = 2x✓2y

c. ✓4x²y = ✓4 × ✓x² × ✓y

= 2 × x × ✓y

= 2x✓y

Therefore, ✓4x²y = 2x✓y

d. ✓16xy² = ✓16 × ✓x × ✓y²

= 4 × ✓x × y

= 4y✓x

Therefore, ✓16xy² = 4y✓x

e. ✓8xy² = ✓8 × ✓x × ✓y²

= ✓4 × ✓2 × ✓x × ✓y²

= 2 × ✓2 × ✓x × y

Note: You probabily forgot to mention the two function. While after some research, I was able to find two functions based on which I would like to solve your query.

Answer:

The y-intercept of the equation will be (0, 4).

Step-by-step explanation:

Considering the assuming functions f(x) and g(x).

[tex]f(x) = -3x - 5[/tex]

[tex]g(x) = f(x)+9[/tex]

So,

[tex]g(x) = (-3x-5)+9[/tex]     ∵ [tex]g(x) = f(x)+9[/tex]

[tex]g(x) = -3x+4[/tex]  

Now, finding the y-intercept

so putting x = 0 in function g(x)

[tex]g(x) = -3(0)+4[/tex]

[tex]g(x) = 0+4[/tex]

[tex]g(x) = 4[/tex]

Therefore, the y-intercept of the equation will be (0, 4).

Answer:

1/2+1/8=5/8

Step-by-step explanation:

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(1/2, 1/8) = 8

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(1/2×4/4)+(1/8×1/1)=?

Complete the multiplication and the equation becomes

4/8+1/8=?

The two fractions now have like denominators so you can add the numerators.

Then:

4+1/8=5/8

This fraction cannot be reduced.

Therefore:

1/2+1/8=5/8
