Answer:

YZ = 8.5

Step-by-step explanation:

Since RY is an angle bisector then the ratio of the sides of the triangle are equal to the corresponding ratio of the base, that is

$\frac{YX}{YZ}$ = $\frac{XR}{ZR}$ , substitute values

$\frac{11.9}{YZ}$ = $\frac{7}{5}$ ( cross- multiply )

7YZ = 59.5 ( divide both sides by 7 )

YZ = 8.5

aksik [14]

Answer:

Step-by-step explanation:

the total is 25.92 and Elaina buys 2.57 eggs. So, you would have to first subtract 2.57 from 25.92 . Then she buys 5 bags of potatoes for x price.

This means that 23.35 (25.92-2.57) will have to be divided by 5 to get the price of 1 bag of potatoes.

x= 4.67

Listed below are prices in dollars for one night at different hotels in a certain region. Find the range, variance, and standar

Vanyuwa [196]

Answer:

Range = $115

Variance = $1915.2857

Standard deviation = $43.764

Step-by-step explanation:

Given the data:

234 160 119 131 218 207 146 141

Arranging in ascending order :

119, 131, 141, 146, 160, 207, 218, 234

The range = maximum - minimum

The range = 234 - 119 = 115

The variance :

Σ(x - mean)²/n-1

The mean = Σx / n

The mean = 1356 / 8 = 169.5

Variance :

Σ(x - mean)² = (119-169.5)² + (131-169.5)² + (141-169.5)² + (146-169.5)² + (160-169.5)² + (207-169.5)² + (218-169.5)² + (234-169.5)² = 13407

n - 1 = 8 - 1 = 7

Variance = 13407 / 7 = 1915.2857

Standard deviation = √variance

Standard deviation = √1915.2857

Standard deviation = $43.764
