A florist has 60 tulips and 72 daffodils. The florist will make bouquets with the same number of tulips and the same number of d
kaheart [24]

Answer: 12

Step-by-step explanation:

Given: A florist has 60 tulips and 72 daffodils.

He wants to make bouquets with the same number of tulips and the same number of daffodils in each using all the flowers.

Then, the greatest number of bouquets the florist can make =  GCD (60,72)

where GCD = Greatest Common Divisor

Prime factorization of 60 and 72 :

60 = 2 x 2 x 3 x 5

72 = 2 x 2 x 2 x 3 x 3

GCD(60,72) = 2 x 2 x 3 = 12

Hence, the greatest number of bouquets the florist can make = 12

Question
maria [59]

Answer:

He needs 16 ounces of raisins and 8 ounces of nuts

Step-by-step explanation:

Let

x -----> the number of ounces of raisins

y -----> the number of ounces of nuts

we know that

x+y=24 -----> equation A

x=2y -----> equation B

Solve the system by substitution

Substitute equation B in equation A and solve for y

(2y)+y=24

3y=24

y=8 ounces of nuts

Find the value of x

x=2(8)=16 ounces of raisins

therefore

He needs 16 ounces of raisins and 8 ounces of nuts

Cholesterol level has a Normal distribution N(170,30), find the first quartile.
geniusboy [140]

Step-by-step explanation:

In statistics, the quartile is a measurement of the spread of values within a dataset above and below the mean via a division of the distribution into four defined intervals. A quartile partitions the data at three points within the distribution.

  • 25% of the data lies below the lower or first quartile, denoted as Q_{1}.

  • 50% of the data lies below the median or second quartile, denoted as Q_{2}.

  • 75% of the data lies below the upper or third quartile, denoted as Q_{3}.

Thus, logically, we know that the remaining 25% of the data lies above the third quartile.

As shown in the figure below, the score that defines the first quartile of the defined normal distribution is the same as the score that, when evaluated in the cumulative density function, \Phi, gives 25% of the area under the bell curve.

To find this z-score, we can use the help of the NORM.INV function in Microsoft Excel, which obtains the inverse of the normal cumulative distribution and the syntax, type into a cell, is as follows:

                                     =\text{NORM.INV(0.25, 170, 30)}

which gives you the value 149.77  (2 s.f.).

This means that 25% of the values of cholesterol levels lie below 149.77.
