A taxi cab charges $0.55 per mile in addition to a $1.75 flat rate fee. Susie has $10 to spend on a taxi cab ride. The taxi driver will not give anyone a ride unless they are going somewhere that is more than 2 miles away. Model Susie’s situation with a system of inequalities.

Answers

Answer 1
The taxi driver doesn't give anyone a ride unless it's 2 miles away, as such you need to add at least $0.55x2 in addition to the $1.75 at the start
1.75+(0.55x2)=2.85
As Susie only has 10 dollars to spend, she can't exceed that. So Susie must spend more than $2.85(minimum from the taxi) and less than $10(her money)
so,
$2.85<Susie<$10

Estimate then find the product 7×7956

Answers

Final answer:

To estimate the product of 7 and 7956, round 7956 to 8000 and then multiply by 7 to get 56,000. The exact product, calculated using the multiplication algorithm, is 55,692.

Explanation:

To estimate the product of 7×7956, we can round 7956 to the nearest thousand which gives us 8000. Then, we multiply 7×8000 to get an estimated product of 56,000. To find the exact product, we multiply 7 by 7956 to get 55,692.

When calculating such a product, we use the multiplication algorithm where we multiply each digit of the second number by the first number and then add up the resulting values.

Here's how you would perform the multiplication step by step:

7×7 = 49, add the carried over 6 to get 55, write down 5 and carry over the 5.

After placing the digits in their correct positions, we get the final answer: 55,692. Therefore, the exact product of 7×7956 is 55,692.

30x - 10x = -20 + 50
20x = 30
x = 3/2 <==

Answer:

[tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Here, the given expression is,

[tex]5(4x-10)+10x=4(2x-3)+2(x-4)[/tex]

By distributive property,

[tex]20x - 50 + 10x = 8x - 12 + 2x - 8[/tex]

By combining like terms,

[tex]30x -50=10x-20[/tex]

Adding 50 on both sides,

[tex]30x=10x-20+50[/tex]

[tex]30x = 10x + 30[/tex]

Subtracting 10x on both sides,

[tex]20x = 30[/tex]

Divide both sides by 20,.

[tex]x=\frac{3}{2}[/tex]

the formula I=square root w/r gives the electric current I amperes that flows through an appliance, where W is the power in watts and R is the resistance in ohms. which set of numbers best describes the value of I for the given values of W and R? ( 42.) W=100,R=25 ( 43.)W=100,R=50

Answers

Final answer:

The value of I for the given values of W and R can be calculated using the formula I = [tex]\sqrt{(W/R)[/tex]. For W = 100 and R = 25, the value of I is 2 amperes. For W = 100 and R = 50, the value of I is approximately 1.41 amperes.

Explanation:

The formula I = [tex]\sqrt{(W/R)[/tex]  gives the electric current in amperes that flows through an appliance, where W is the power in watts and R is the resistance in ohms.

To determine the value of I for the given values of W and R, we can simply substitute the values into the formula. For the first set of numbers, W = 100 and R = 25:

[tex]I = \sqrt{(100/25)} = \sqrt{(4)} = 2[/tex] amperes.

For the second set of numbers, W = 100 and R = 50:

[tex]I = \sqrt{(100/50)} = \sqrt{(2) }[/tex]≈ 1.41 amperes.

Therefore, the value of I for the first set of numbers (W = 100, R = 25) is 2 amperes, and the value of I for the second set of numbers (W = 100, R = 50) is approximately 1.41 amperes.

Look at the radian measure for every 30 degrees and 45 degrees in the Unit Circle. Explain how finding the exact measure in quadrant one can help you determine the remaining exact radian measures.

Answers

Google radian measures on the unit circle for lots of images of completed unit circles with these radian measurements. But the core idea is that if you can find the 30° and 45° radian measures (π/6 and π/4 respectively) to move to the corresponding angle in quadrant 2, you'd just need to add π/2 (90°) to that value, to find the values in quadrant 3 add π (180°), quadrant 4 add 3π/4 or you could also just minus π/2 to move 90° in the opposite direction. Say I wanted to find the 45° angle in quadrant 3, measured from the 0° line on the unit circle, in radians. I could say I know 45° is π/4 in quadrant 1, so to move it to quadrant 3, I need to add π or 180° to it. π/4 + π = π/4 + 4π/4 = 5π/4 which is the angle we need in radians.

If you subtract (a-4) from (4a+16), the new equation to work with would be 3a + 12. And if the difference of these two equations is 3a + 12, which would give an answer of -25, (pictured 3a + 12 = -25), by using algebra we could try a = -13/3 or a equals negative 13 over three. I hope this helps

If cba represents three numbers multiplied together, what property allows you to rearrange the factors to read abc?

Answers

Final answer:

The commutative property allows you to rearrange the factors of a multiplication problem.

Explanation:

The property that allows you to rearrange the factors of a multiplication problem is the commutative property. This property states that the order of the factors can be changed without changing the product. In this case, if cba represents three numbers multiplied together, you can rearrange the factors to read abc because multiplying in any order will give you the same product.

For example, if c = 2, b = 3, and a = 4, then cba = 2 * 3 * 4 = 24. Rearranging the factors to abc gives abc = 4 * 3 * 2 = 24, which is the same product.

P(−1.95996398454005≤X≤1.95996398454005)=0.95

Answer:

92.67% probability of obtaining a z value between -1.9 to 1.7.

Step-by-step explanation:

Normal probability distribution

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

For a standard normal distribution, the probability of obtaining a z value between -1.9 to 1.7 is

This probability is the pvalue of z = 1.7 subtracted by the pvalue of z = -1.9.

z = 1.7 has a pvalue of 0.9554.

z = -1.9 has a pvalue of 0.0287.

So there is a 0.9554-0.0287 = 0.9267 = 92.67% probability of obtaining a z value between -1.9 to 1.7.

Suppose there is a test for esophageal cancer that is 95% accurate both on those that do and those that do not have esophageal cancer. if 0.7 percent of the population has esophageal cancer, compute the probability that a person has this cancer, given that his or her test results indicates so.

Answers

It was already stated that the probability that the population may have esophageal cancer is 0.7 percent. However, the additional statement that the accuracy is 95% will affect the probability as follows:

Probability = (0.007)(0.95) = 0.00665 or 0.665%

So instead of 0.7%, the probability will decreased to 0.665% because of the accuracy.

box contains 15 items,4 of which are defective and 11 are good. Two items are selected. What is probability that the first is good and the second defective?

Answers

The probability of the first item being good is 11/15.
Since we have taken 1 item out the remaining total is now 14, so the probability of getting a defective item is now 4/14.
Now you multiply the probabilities together to get (11/15)(2/7)=22/105

Final answer:

The probability that the first item selected is good and the second item is defective is 22/105.

Explanation:

To find the probability that the first item selected is good and the second item is defective, we need to consider the total number of items, the number of good items, and the number of defective items.

The total number of items is 15, with 11 being good and 4 being defective. When we select the first item, there are 15 options, out of which 11 are good. Therefore, the probability of selecting a good item first is 11/15.

After selecting the first item, there are now 14 items left in the box, with 10 being good and 4 being defective. When we select the second item, there are 14 options, out of which 4 are defective. Therefore, the probability of selecting a defective item second is 4/14, which simplifies to 2/7.

To find the probability that both events occur, we multiply the probabilities: (11/15) * (2/7) = 22/105.
