Answer:

24 m^2

Step-by-step explanation:

The area of a kite is the product of the diagonals divided by 2.

If the diagonals have lengths a and b, then area = ab/2

area = ab/2

a = horizontal diagonal = 2 m + 6 m = 8 m

b = vertical diagonal = 3 m + 3 m = 6 m

area = (8 m)(6 m)/2 = (48 m^2)/2 = 24 m^2

For a sample of n = 36 that has a sample variance of 1,296, what is the estimated standard error for the sample? 6 37 36 6. 9

Liula [17]

The estimated standard error for the sample is 6

Given,

Sample size, n = 36

Sample variance, $s^{2}$ = 1296

Standard deviation, s = √1296

= 36

Standard error, SE = $\frac{s}{\sqrt{n} }$

= $\frac{36}{\sqrt{36} }$

= $\frac{36}{6}$

= 6

Concept

Sample size is the number of participants or observations included in a study. It is denoted by ‘n’

Sample variance is a measure of the degree to which the numbers in a list are spread out. It is denoted by ' $s^{2}$ '

Standard deviation is a measure of how dispersed the data is in relation to the mean. It is denoted by ‘s’

Lucas is making accessories for the soccer team. He uses 883.68 inches of fabric on headbands for 46 players and 2 coaches. He a

zimovet [89]

The total fabric used for headband and wristband of a player was: 27.84 inches

Step-by-step explanation:

The question will be solved step by step.

So,

Total ribbon used for headbands = 883.68 inches

Total number of people for whom headbands were made = 46 players + 2 coaches = 48 inches

so the headband for one person will use fabric: $\frac{883.68}{48}\\= 18.41\ inches$

Then

Total fabric used for wristbands = 433.78 inches

Total players = 46

$Fabri\ for\ one\ player's\ wristband = \frac{433.78}{46}\\=9.43\ inches$

Total fabric for one player = 18.41 + 9.43 = 27.84 inches

Hence,

The total fabric used for headband and wristband of a player was: 27.84 inches
