Lucy workrate 1/3.5 = reciprocal of 7/2 = 2/7

combined workrate: 1/5 + 2/7 = 17/35

they will mow the lawn in  35/17 = 2 and 1/17 hours

2 hours 3 1/2 mins

Step-by-step explanation:

The expression that represents the amount spent by each woman is [tex]9 +1.35 + \frac{1}{2} \times (3.50 +1.74)[/tex]

The table entries are given as:

Item                      Cost (dollars)

Adult ticket                   9

Child ticket                   6

Drink                           1.35

Popcorn                     3.50

Veggie cup                1.74

Soft pretzel                2.65

Apple slices               3.85

From the question, we understand that, each woman bought the following a drink

The initial cost is:

[tex]Cost= 1.35[/tex]

They also shared one popcorn and one veggie cup.

Half of the sum of these amounts would be added to the cost.

So, we have

[tex]Cost= 1.35 + \frac{1}{2} \times (3.50 +1.74)[/tex]

Lastly, the cost of an adult ticket would be added to the above cost

[tex]Cost= 9 +1.35 + \frac{1}{2} \times (3.50 +1.74)[/tex]

Hence, the expression that represents the cost is [tex]9 +1.35 + \frac{1}{2} \times (3.50 +1.74)[/tex]

Answer:

B

Step-by-step explanation:

The first row of the table shows (x,y) = (-4,2). If we add in (-4,1), then we will re-use x = -4 a second time. The input x = -4 leads to multiple outputs of 2 and 1 at the same time. Visually the two points stack on each other to form a vertical line, therefore failing the vertical line test.

The second answer choice (1,-4) looks like your teacher might be trying to trick you or place out a trick/trap answer due to how similar it looks. This point can be added and the function is still valid because x = 1 hasn't been used yet in the table.

V =108 ft^3

Step-by-step explanation:

The volume is found by

V = Bh  where B is the area of the base

B = the area of the trapezoid

B = 1/2 (b1+b2)*h of the trapezoid

B = 1/2(4+6)*4 = 1/2(10)*4 = 20

Now we can find the volume

Answer:

  d(t) = -20t -260

Step-by-step explanation:

We are given two points ...

  (t, d) = (3, -320) and (8, -420)

The 2-point form of the equation of a line can be useful when 2 points are given.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

Substituting the given points, we have ...

  d(t) = (-420 -(-320))/(8 -3)(t -3) -320

  d(t) = -20(t -3) -320

  d(t) = -20t -260

  D. Neither Gordon nor Tess

Step-by-step explanation:

The vertices ABC are in clockwise order. The corresponding vertices FGE are also in clockwise order. On this basis, you can say that there cannot be a single reflection (as across x=1), because that would reverse the order to counterclockwise. Gordon cannot be correct.

The left-right orientation of vertices A and C is reversed to a right-left orientation for corresponding vertices F and E. This means two reflections or a rotation is involved. Translation cannot reverse the orientation like this, so Tess cannot be correct.

ΔFGE and ΔABC are a reflection of each other across the origin, equivalent to the two reflections "across the x-axis" and "across the y-axis." This is also equivalent to a rotation of 180° about the origin.

Neither Gordon nor Tess is correct.

Answer:

[tex]z=\frac{0.923-0.631}{\sqrt{0.759(1-0.759)(\frac{1}{840}+\frac{1}{1077})}}=14.83[/tex]    

The p value for this case would be:

[tex]p_v =2*P(Z>14.83)\approx 0[/tex]    

For this case the p value is very low so we have enough evidence to reject the null hypothesis and we can conclude that the true proportion of employment levels for men compared to woman were different

Step-by-step explanation:

Information given

[tex]X_{1}=775[/tex] represent the number of people fully employed men

[tex]X_{2}=680[/tex] represent the number of people fully employed women

[tex]n_{1}=840[/tex] sample 1 selected  

[tex]n_{2}=1077[/tex] sample 2 selected  

[tex]p_{1}=\frac{775}{840}=0.923[/tex] represent the proportion estimated for male employed

[tex]p_{2}=\frac{680}{1077}=0.631[/tex] represent the proportion estimated for women employed

[tex]\hat p[/tex] represent the pooled estimate of p

z would represent the statistic

[tex]p_v[/tex] represent the value for the test

System of hypothesis

We want to test the claim that the employment levels for men compared to woman were different, the system of hypothesis would be:    

Null hypothesis:[tex]p_{1} = p_{2}[/tex]    

Alternative hypothesis:[tex]p_{1} \neq p_{2}[/tex]    

For this case the statistic is given by:

[tex]z=\frac{p_{1}-p_{2}}{\sqrt{\hat p (1-\hat p)(\frac{1}{n_{1}}+\frac{1}{n_{2}})}}[/tex]   (1)  

Where [tex]\hat p=\frac{X_{1}+X_{2}}{n_{1}+n_{2}}=\frac{775+680}{840+1077}=0.759[/tex]  

Replacing the info given we got:

[tex]z=\frac{0.923-0.631}{\sqrt{0.759(1-0.759)(\frac{1}{840}+\frac{1}{1077})}}=14.83[/tex]    

The p value for this case would be:

[tex]p_v =2*P(Z>14.83)\approx 0[/tex]    

For this case the p value is very low so we have enough evidence to reject the null hypothesis and we can conclude that the true proportion of employment levels for men compared to woman were different.

Answer:Simplifying

5(x + 2) = 3(x + 8)

Reorder the terms:

5(2 + x) = 3(x + 8)

(2 * 5 + x * 5) = 3(x + 8)

(10 + 5x) = 3(x + 8)

Reorder the terms:

10 + 5x = 3(8 + x)

10 + 5x = (8 * 3 + x * 3)

10 + 5x = (24 + 3x)

Solving

10 + 5x = 24 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

10 + 5x + -3x = 24 + 3x + -3x

Combine like terms: 5x + -3x = 2x

10 + 2x = 24 + 3x + -3x

Combine like terms: 3x + -3x = 0

10 + 2x = 24 + 0

10 + 2x = 24

Add '-10' to each side of the equation.

10 + -10 + 2x = 24 + -10

Combine like terms: 10 + -10 = 0

0 + 2x = 24 + -10

2x = 24 + -10

Combine like terms: 24 + -10 = 14

2x = 14

Divide each side by '2'.

x = 7

Simplifying

x = 7

ANSWER A

If two events is mutually exclusive, it means that they cannot occur at the same time. Coin tossing is an example of something being mutually exclusive, landing on heads and tails cannot happen at the same time; it's either one or the other! In our case, this is not the case. The pizza having mushrooms on it does not affect the type of crust. The crust type and mushrooms can happen at the same time; you can have both! Therefore, Thick Crust Pizza and Pizza with mushrooms are not mutually exclusive.

ANSWER B

ANSWER 1: We know that there are nine pizzas in the oven. Looking at the chart, we see that three total pizzas have thick crust. One of them has no mushrooms and two of them do have mushrooms. This probability is 3/9, or 1/3.

ANSWER 2: We want to find a pizza that has both mushrooms and a thick crust. As we saw when solving for Answer 1, we have that 2 pizzas have both thick crust and mushrooms. This probability is 2/9.

ANSWER C

A dependent event is one that will depend on the result before it. Thick crust pizza and mushrooms do not affect each other at all; they do not depend on each other. They both do their own thing. We need to justify with things we found in Answer B. Well, when we added the event of mushrooms our probability decreased. If one of the events depended on the other, the probability would have definitely increased.  Therefore, these events are both independent.

I hope that this helps you! Have a wonderful day!

A. Repeat the simulation several more times

Step-by-step explanation:

The purpose of the simulation model is to represent the effectivity of the passes.

The proportion of successful passes is 60%.

As we have 10 digits available, 6 (digits from 0 to 5) are used for the outcome "the pass is completed" and 4 (digits 6, 7, 8, and 9) to represent the outcome "the pass is not completed". This is correct, as it represents a probability of 60% of having a successful pass.

But to have a representative distribution of the possible and probable results, the simulation have to run enough times to have a stable distribution of the results.

55 percent of 300 is equal to 165.

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100.

Given,

55% of 300

55% can be written as fraction 55/100

= (55/100) × 300

Dividing 300 by 100

Answer: 5/11

Step-by-step explanation:

The probability of picking a dime is [tex]\frac{2}{11}[/tex].

The measure of happening or non-happening of the outcomes of a random experiment is called probability.

P(E) = Number of favorable outcomes/ total number of outcomes

Where,

P(E) is the probability of an event.

According to the given question.

Total number of quarters coins = 5

Total number of dimes coins = 2

Total number of pennies coins = 4

Therefore,

The total number of coins in a bag = 5 + 4 + 2 = 11

⇒ Total number of outcomes = 11

So, the probability of picking a dime coin is given by

P(E) = total number of dime coins/ total number of coins in a bag

⇒[tex]P(E) = \frac{2}{11}[/tex]

Hence, the probability of picking a dime is [tex]\frac{2}{11}[/tex].
