A candy shop sells a box of chocolate for $30. Which is the lnropper way to use this sentence?​

Answer:

117

Step-by-step explanation:

Hi, If you were to add 75 to 42, you would get 117. Since a triangle's angles all have to add up to 180, the last angle would be 63. However, you are looking for the outside angle, which would then just be 117. Hope this is right!

Answer:

the better buy is that from the second store as it is cheaper than that purchased from the first store

Step-by-step explanation:

Given that :

First store :

Amount paid = $12.16

Pounds of shrimps = 4.07

Unit price :

Amount paid / pounds of shrimps

$12.16 / 4.07 = $2.9877

= $2.99 = 299 cents

second store :

Amount paid = $14.99

Pounds of shrimps = 5.11

Unit price :

Amount paid / pounds of shrimps

$14.99 / 5.11 = $2.933

= 2.93 = 293 cents

Hence, the better buy is that from the second store as it is cheaper than that purchased from the first store

Answer:

Answer:

0.2047

0.2377

Step-by-step explanation:

1.

What we have here is a binomial distribution

Probability p = 0.12

N = number of students in the class = 30

Probability of finding 4 left handers

P(x = 4) = 30C4 x (0.12)⁴ x (0.88)²⁶

= 27405 x 0.00020736 x 0.03602047835

= 0.2047

2.

This is also a binomial distribution

N = 10 p = 0.65

P(of 6 knowledgeable fans)

= 10C6 x (0.65)⁶ x (0.35)⁴

= 210 x 0.0754189 x 0.01500625

= 0.2377

Answer:

Option D

Step-by-step explanation:

Set of data in terms of ordered pairs represents a function when output value of each input value is different.

Option A

Since, for every value of x there is a different value of y, it's a function.

Option B

In each ordered pair, for every value of x there is a different value of y.

Therefore, it's a function.

Option C

From the given graph, for every value of x there is a different value of y.

Therefore, it's a function.

Option D

From the given set of ordered pairs we find for x = 1 there are two values of y (y = 4 and 3).

Therefore, the given set of ordered pairs doesn't represent a function.

Option D is the answer.

Answer:

$26.60

Step-by-step explanation:

Calculation for the marginal cost of a calculus textbook

Marginal cost =($52,900-$26,300)/(2,000-1,000)

Marginal cost=$26,600/1,000

Marginal cost=$26.60

Or

First step

$52,900=2,000x +c equation (1)

$26,300= 1,000x+c equations (2)

Second step is to subtract equation (1) from equation (2)

$52,900=2,000x +c equation (1)

-$26,300= 1000x+c equations (2)

$26,600=1,000x

Third step is to find the marginal cost

$26,600=1,000x

x=26,600/1,000

x=$26.60

Therefore the marginal cost of a calculus textbook will be $26.60

Answer:

[tex]y =-\frac{1}{2}x + 8[/tex]

Step-by-step explanation:

Given

Perpendicular to [tex]y = 2x + 1[/tex]

Pass through [tex](4,6)[/tex]

Required

Determine the line equation

First, we need to determine the slope of [tex]y = 2x + 1[/tex]

An equation is of the form:

[tex]y = mx + b[/tex]

Where

[tex]m = slope[/tex]

In this case:

[tex]m =2[/tex]

Next, we determine the slope of the second line.

Since both lines are perpendicular, the second line has a slope of:

[tex]m_1 = \frac{-1}{m}[/tex]

[tex]m_1 = \frac{-1}{2}[/tex]

[tex]m_1 = -\frac{1}{2}[/tex]

Since this line passes through (4,6); The equation is calculated as thus:

[tex]y - y_1 = m_1(x - x_1)[/tex]

Where

[tex](x_1,y_1) = (4,6)[/tex]

This gives:

[tex]y - 6=-\frac{1}{2}(x - 4)[/tex]

Open bracket

[tex]y - 6=-\frac{1}{2}x + 2[/tex]

Add 6 to both sides

[tex]y +6- 6=-\frac{1}{2}x + 2+6[/tex]

[tex]y =-\frac{1}{2}x + 8[/tex]

b. Decision variables

Step-by-step explanation:

The decision variable is the variable that decides that what would be the output. It presents the final solution.

Since in the given situation it is mentioned that the Mike uses linear programming for formulating a problem now the choices that chose for minimize or maximize the value would be the decision variables

Hence, the correct option is b.

Objective function is a function used in linear programming (LP) so as to maximize or minimize.

Linear programming are system of linear constraints used to optimize or solve a problem. The problem is being solved by selecting the variables that would be used to maximize or minimize the objective function from a list of several objective functions.

Answer:

disproportionate stratified sample

Step-by-step explanation:

Based on the given information we can say that Abel's sample is a disproportionate stratified sample. This is the case mainly because the department worker population ranges from 40 to 120 workers. This changing population makes the 10 workers that were chosen for the sample not proportionate to the entire population. Therefore, under different population sizes workers have different chances of getting selected for the study which ultimately creates different results.

Answer:

ok so he needs to buy two different collored shirts

Step-by-step explanation:

Answer:

1) dA/dt = -21 cm²/s and Area is decreasing

2)dP/dt = 0 and perimeter is constant

3) dD/dt = 21/13 cm/s and diagonal is increasing

Step-by-step explanation:

We are given that;

length l of a rectangle is decreasing at a rate of 3 cm/sec.

Thus, dl/dt = -3 cm/sec

Also, the width w is increasing at a rate of 3 cm/sec. Thus;

dw/dt = 3 cm/sec

When l=5 cm and w=12 cm;

A) Area is given by the formula;

A = lw

The rate at which area is increasing is;

dA/dt = l(dw/dt) + w(dl/dt)

Plugging in the relevant values;

dA/dt = 5(3) + 12(-3)

dA/dt = 15 - 36

dA/dt = -21 cm²/s

This is less than 0.thus, A is decreasing.

B) Formula for perimeter is;

P = 2l + 2w

rate of change of perimeter is;

dP/dt = 2(dw/dt) + 2(dl/dt)

Plugging in the relevant values, we have;

dP/dt = 2(-3) + 2(3)

dP/dt = 0

Thus,Perimeter is constant

C) the length of the diagonal of a rectangle is given by;

D = √(w² + l²)

Rate of change of diagonal is;

dD/dt = [2w(dw/dt) + 2l(dl/dt)]/(2√(w² + l²))

2 will cancel out in numerator and denominator to give;

dD/dt = [w(dw/dt) + l(dl/dt)]/(√(w² + l²))

Plugging in the relevant values gives;

dD/dt = [12(3) + 5(-3)]/(√(12² + 5²))

dD/dt = (36 - 15)/13

dD/dt = 21/13 cm/s

This is greater than 0.

Thus, diagonal is increasing.

Answer:

y = x - 5

Step-by-step explanation:

Comparing the given y = x - 7 to y = mx + b, we see that the slope is +1.

In y = x + b we replace y with -11 and x with -6 to determine the y-intercept, b:

-11 = -6  + b

Then b must be -5, and so the desired new equation is

y = x - 5

Step-by-step explanation:

Answer:

f =0.5

Isolate the variable by dividing each side by factors that don't contain the variable.

______________________________

 - We subtract 2.9 from both sides because we need to get rid of any extra numbers on the opposite side of the equal sign. To do so, you do the opposite of what you see: We have a positive 2.9, so we subtract.

Equation at the end of Step 1:

 - We divide 3 from both sides because the 3 is attached to the variable and we need to get the variable alone. So to do so we have to divide by 3 on each side.

 - 0.5 is equal to [tex]\frac{1}{2}[/tex] as a fraction.
