Elina [12.6K]

Answer:

9/4z cups

Step-by-step explanation:

Alex recipe uses 7 1/2 cups of flour for 5 batches

Cups of flour per batch = 7 1/2 cups ÷ 5 batches

= 15/2 ÷ 5

= 15/2 × 1/5

= (15*1)/(2*5)

= 15/10

Alex recipe per batch= 3/2 cups of flour per batch

paytons recipe uses 3/4 cup of flour more per batch than alexs recipe

Payton's recipe per batch = Alex recipe per batch + 3/4 cups

= 3/2 + 3/4

= (6+3)/4

= 9/4 cups of flour

Payton's recipe per batch = 9/4 cups of flour

What expression can be used to determine the number of cups of flour used to make z batches of paytons pancake recipe

Payton's recipe for z batches = Payton's recipe per batch * number of batches

= 9/4 cups * z batches

= 9/4z cups

Payton's recipe for z batches = 9/4z cups

Answer:

11/3 = 3 2/3 ≈ 3.66667

Step-by-step explanation:

The external angle is half the difference of the intercepted arcs:

3x = (1/2)((9x +25) -36)

6x = 9x -11

11 = 3x . . . . . . . add 11-6x

11/3 = x

Answer:

(a) median = 57

(b) Q1=50 Q3=63.5

(c)D1 = 41 D9=67

(d)P33= 51

Step-by-step explanation:

(a) The numbers are arranged in ascending order, and there are even number of calls. So the median will be the average of the middle terms.

middle terms are 55 and 59

Median = $\frac{55+59}{2}$

median= 57

(b) First quarter Q1 = $\frac{1}{4} number of calls$ th

= $\frac{1}{4} *30$ th

= 7.5th

so the first quarter lies in the 7.5th= (7+0.5)th term

So we multiply 0.5 by the difference of the 7th and 8th term

=0.5 *0= 0

Q1 = 50+0=50

Q3= $\frac{3}{4} number of calls$ th

= $\frac{3}{4} *30$ th

=22.5th = (22+0.5)th term

So we multiply 0.5 by the difference of the 22th and 23rd term

= 0.5*1=0.5

Q3= 63+0.5=63.5

(c) First decile (D1) = $\frac{1}{10} number of calls$ th

= $\frac{1}{10} *30$ th

= 3rd term

D1= 41

D9= $\frac{9}{10} number of calls$ th

= $\frac{9}{10} *30$ th

=27th term

D9 = 67

(d) 33rd percentile = $\frac{33}{100} number of calls$ th

= $\frac{33}{100} *30$ th

= 9.9th term = (9 +0.9)th

Multiply 0.9 by the difference between the 9th and tenth term.

= 0.9*0 =0

P33 = 51
