Answer:

x-intercept = 5

y-intercept = 350

Step-by-step explanation:

Assuming that h=x and m=y, when x is at 0 the y is at it's intercept giving you a y-intercept of 350. When y is at 0 the x is at it's intercept giving you an x-intercept of 5.

Answer:

y=3x+1

Step-by-step explanation:

4--2=6

1--1=2

6/2=3

slope is 3

4=3(1)+b

4=3+b

4-3=3-3+b

1=b

1 is the y intercept

Answer:

    y = 3x + 1

Step-by-step explanation:

(x₁, y₁) = (-1, -2)   & (x₂ , y₂) = (1, 4)

[tex]slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]

        [tex]= \frac{4-[-2]}{1-[-1]}\\\\= \frac{4+2}{1+1}\\\\= \frac{6}{2}\\\\= 3[/tex]

m = 3

y -y₁ = m(x - x₁)

y - [-2] = 3(x - [-1])

y + 2 = 3(x +1)

y + 2 = 3x + 3

      y = 3x + 3 -2

      y = 3x + 1

Answer: Circumference

Step-by-step explanation: The distance around a circle on the other hand is called the circumference (c). Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r). Consider marking this answer as brainliest if it helped you out.

Solution :

[tex]$T_1$[/tex] = k.n (cost proportional to quantity)

35000 = k . 700

k = [tex]$\frac{35000}{700}$[/tex]

  = 50

So [tex]$T_1$[/tex] = 50 n

Now [tex]$T_2=Pn^2$[/tex]     (cost proportional to square of n)

[tex]$3430= P(700)^2$[/tex]

3430 = 490000 P

[tex]$P = \frac{3430}{490000}$[/tex]

[tex]$P = \frac{7}{1000}$[/tex]

[tex]$T_2=\frac{7}{1000}n^2$[/tex]

Now, [tex]$T_3= 7000$[/tex]   (fixed)

Therefore,

Total, [tex]$T=T_1+T_2+T_3$[/tex]

[tex]$T=50n+\frac{7}{1000}n^2+7000$[/tex]

[tex]$T=0.007n^2+50n+7000$[/tex]

The required formula in terms of T and n is T = 0.000[tex]n^{2}[/tex] + 50 n +7000.

Given that ,

The total daily cost = T

When producing and storing n items is the sum of production, storage and fixed costs.

The manufacturing cost of a product when 700 items produced = $35000 dollars per day.

Daily storage cost of when 700 items are stored = $3430 dollars

We have write the formula in terms of total daily cost T and n stored items.

According to the question,

The cost to manufacture a product is proportional to the quantity produced, with a cost of $35000 dollars per day when 700 items are produced.

Where ,total daily cost T and n stored items.

[tex]T_1 = k . n[/tex]

$35000 =  k.700

[tex]k = \frac{35000}{700}[/tex]

k = $50

The cost to store n items is proportional to the square of n, with a daily storage cost of $3430 dollars when 700 items are stored.

[tex]T_2 = pn^{2}[/tex]

$3430 = P [tex](700)^{2}[/tex]

$3430 = P 490000

[tex]P = \frac{3430}{490000} \\\\P = \frac{7}{1000}[/tex]

There is a fixed daily cost of $7000.

[tex]T_3 = 7000[/tex]

Combine all the equation ,

Where T = [tex]T_1 = T_2 = T_3[/tex] and p = k =n

T = 0.000[tex]n^{2}[/tex] + 50 n +7000

Hence,  The required formula in terms of T and n is T = 0.000[tex]n^{2}[/tex] + 50 n +7000.

Step-by-step explanation:

Answer:

Step-by-step explanation:

5^2-3^2= 16

25-9=16

Answer:

1.35%

Step-by-step explanation:

Suppose that IQ scores have a bell-shaped distribution with a mean of 104 and a standard deviation of 15. Using the empirical rule, what ? Please do not round your answer.

Empirical rule formula states that:

95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .

We don't know the number of Standard deviation yet , hence:

Mean = 104

Standard deviation = 15.

At least 59

Hence:

104 - 15x = 59

104 - 59 = 15x

45 = 15x

x = 45/15

x = 3

Hence, At least 59 is 3 standard deviations away from the mean on one side of the distribution thus,

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .

100% - 99.7%

= 0.003

Since it is on one side of the distribution:

= 1.5% - 0.3%

= 0.015 - 0.0015

= 0.00135

Converting to percentage

= 1.35%

The percentage of IQ scores that are at least 59 is 1.35%

Answer: the third i think

Answer:

21 boys

Step-by-step explanation:

2:3=14:x you cross multiply this to find the amount of boys

2x=42

x=21

There are 21 boys in the class.

Basically, solve what you have there with cross-multiplication.

2x = 14 x 3

2x = 42

Then divide both sides by 2. (edited it bc didn't say what you actually had to do)

2x ÷ 2 = 42 ÷ 2

x = 21.

There are 21 boys in the class.

B. Set the alpha level at 0.05.

Step-by-step explanation:

Hypothesis testing is a procedure whereby a researcher determines if the null hypothesis is rejected or accepted, depending on the significant level or the alpha level. When a type I error is made, the null hypothesis is rejected even though it is correct. To solve this problem, the significant or alpha level is set to 5% or 0.05.
