Answer:

x = -8/29 = -0.276

Step-by-step explanation:

Step 1 :

Solving a Single Variable Equation :

1.1 Solve : 29x+8 = 0

Subtract 8 from both sides of the equation :

29x = -8

Divide both sides of the equation by 29:

x = -8/29 = -0.276

One solution was found :

x = -8/29 = -0.276

Answer:

x = - 8/29

Step-by-step explanation:

32x + 5 = 3x - 3

Collect like terms

32x - 3x = -5 - 3

29x = -8

Divide both sides by 29 to get x

29x/29 = -8/29

x = - 8/29

Answer: If the 40% off coupon is used, the subtotal will be $12.69

The gratuity would be exactly $4.23 (He will probably leave $4.25)

Step-by-step explanation: To find out the amount of the discount

.40 × 21.15 = 8.46

To find the new subtotal, subtract 12.15 - 8.46 = 12.69

To figure the tip: .20 × 21.15 = 4.23

Changing the percent to a decimal means divide the 20 by 100.

Coach Evans recorded the height, in inches of each player on his team. The results are shown.

marysya [2.9K]

Answer:

Step-by-step explanation:

Given:

Team heights (inches):

61, 57, 63, 62, 60, 64, 60, 62, 63

To find: IQRs (interquartile ranges) of the heights for the team

Solution:

A quartile divides the number of terms in the data into four more or less equal parts that is quarters.

For a set of data, a number for which 25% of the data is less than that number is known as the first quartile $(Q_1)$

For a set of data, a number for which 75% of the data is less than that number is known as the third quartile $(Q_3)$

Terms in arranged in ascending order:

$57,60,60,61,62,62,63,63,64$

Number of terms = 9

As number of terms is odd, exclude the middle term that is 62.

$Q_1$ is median of terms $57,60,60,61$

Number of terms (n) = 4

Median = $\frac{(\frac{n}{2})^{th} +(\frac{n}{2}+1)^{th} }{2} =\frac{2^{nd}+3^{rd}}{2} =\frac{60+60}{2}=\frac{120}{2}=60$

So, $Q_1=60$

So, 25% of the heights of a team is less than 60 inches

$Q_3$ is the median of terms $62,63,63,64$

Median = $\frac{(\frac{n}{2})^{th} +(\frac{n}{2}+1)^{th} }{2} =\frac{2^{nd}+3^{rd}}{2} =\frac{63+63}{2}=\frac{126}{2}=63$

So, $Q_3=63$

So, 75% of the heights of a team is less than 63 inches

Interquartile range = $Q_3-Q_1=63-60=3$

The interquartile range is a measure of variability on dividing a data set into quartiles.

The interquartile range is the range of the middle 50% of the terms in the data.

So, 3 is the range of the middle 50% of the heights of the students.

If the xy-plane, the graph of y=x^2 and the circle with center (0,1) and radious 3 have how many points of intersection?

PSYCHO15rus [73]

<span>The answer to this question is c, two. The top arc of the circle intersects the y=x^2 as each 'limb' extends into infinity. The part of the circle below the x-axis does not intersect the circle. The y=x^2 curve does not dip below the x-axis, but does extend into infinity on both the negative x-axis and positive x-axis.</span>
