Step-by-step explanation:

the figure is a square so all four sides are equal and has 90 degree corners.

the diagonal has the value of 6 so:

6^2=s^2+s^2

36=2s^2

s^2=18  or sq rt 18 which would be 3(sq rt 2)

A basketball coach kept stats for his team in free throw percentage and steals (among others). At the last game, Erin's free throw percentage was 79% and she had 4 steals. The team averaged 87% from the free throw line with a standard deviation of 12 and they averaged 7 steals with a standard deviation of 3. In which category did Erin do better compared with her team

Answers

Answer:

Due to the higher z-score, she did better in the free throw category.

Step-by-step explanation:

Z-score:

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.

In this question:

She did better in the category that she had the higher z-score:

Free-throws:

Her free throw percentage was 79%, which means that [tex]X = 79[/tex]

The team averaged 87% from the free throw line with a standard deviation of 12, which means that [tex]\mu = 87, \sigma = 12[/tex]. So

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

[tex]Z = \frac{79 - 87}{12}[/tex]

[tex]Z = -0.67[/tex]

Steals:

She had 4 steals, which means that [tex]X = 4[/tex]

Averaged 7 steals with a standard deviation of 3, which means that [tex]\mu = 7, \sigma = 3[/tex]. So

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

[tex]Z = \frac{4 - 7}{3}[/tex]

[tex]Z = -1[/tex]

Due to the higher z-score, she did better in the free throw category.

WILL MARK BRAINLYIST what are the values of X,Y, and z

Answers

Answer:

x=111, y=36, z=76

Step-by-step explanation:

x = 45 + 66

Therefore x is 111 degrees

To find y, we will use the triangle method. We know that a triangle adds to 180, and so do two adjacent angles on a straight line.

180-66 = 114

180 - 114 - 30 = y

Therefore y is 36 degrees.

Same principles with z.

180- 119 = 61

180 - 61 - 43 = z

Therefore, z is 76 degrees.

Final:
x = 111
y = 36
z = 76

It is easy to make a delicious-looking hamburger at home. But would this hamburger still look delicious after it sat on your kitchen table under very bright lights for six or seven hours? If someone took a picture or made a video of this hamburger after the seventh hour, would anyone want to eat it? More importantly, do you think you could get millions of people to pay money for this hamburger?These are the questions that fast food companies worry about when they produce commercials or print ads for their products. Video and photo shoots often last many hours. The lights that the photographers use can be extremely hot. These conditions can cause the food to look quite unappealing to potential consumers. Because of this, the menu items that you see in fast food commercials are probably not actually edible.Lets use the hamburger as an example. The first step towards building the perfect commercial hamburger is the bun. The food stylista person employed by the company to make sure the products look perfectsorts through hundreds of buns until he or she finds one with no wrinkles. Next, the stylist carefully rearranges the sesame seeds on the bun using glue and tweezers for maximum visual appeal. The bun is then sprayed with a waterproofing solution so that it will not get soggy from contact with other ingredients, the lights, or the humidity in the room.Next, the food stylist shapes a meat patty into a perfect circle. Only the outside of the meat gets cookedthe inside is left raw so that the meat remains moist. The food stylist then paints the outside of the meat patty with a mixture of oil, molasses, and brown food coloring. Grill marks are either painted on or seared into the meat using hot metal skewers.Finally, the food stylist searches through dozens of tomatoes and heads of lettuce to find the best-looking produce. One leaf of the crispest lettuce and one center slice of the reddest tomato are selected and then sprayed with glycerin to keep them looking fresh.So the next time you see a delectable hamburger in a fast food commercial, remember: youre actually looking at glue, paint, raw meat, and glycerin!
