Answer:

There are 36 blueberries and 12 Strawberries! I hope this helps you out. :)

Step-by-step explanation:

Hi, so I have a really easy way for you to do this and understand! :)

Basically, you can just add the two numbers in the ratio together and divide that from the bigger total. For example, 9+3=12 and 48/12 is 4. Then you can just multiply each beginning ratio by four and you have your answer: 9*4=36 and 3*4 equals 12. An what does 12+36 equal? 48.

Answer:

36 blueberries and 12 strawberries

Step-by-step explanation:

Given that

Total number of berries in the bowl = 48

And, the ratio of blueberries to strawberries is 9 to 3

So by considering the above information, the each berry contains buy following equation

9X + 3X = 48

12X = 48

So, X = 4

Now the blueberries is 9X.

So, 9 × 4 = 36

And, the strawberries is 3X.

So, 3 × 4 = 12

Y=5/2x-19 and 5x+2y=-8 a perpendicular,parallel or intersecting lines?
dimaraw [331]

Answer:

There intersecting lines

Step-by-step explanation:

5x+2y=-8

-5x            -5x

2y=-8 -5x

/2   /2  /2

y=-4 -5/2x also

y=-5/2x - 4

&

y=5/2x - 19

neither parallel (slope is not the same)

or perpendicular (slope is not reciprocal or opposite signed)

hope i helped

If you have 66 data observations in a sample, how many classes (bins) does the sturges' rule recommend for you to construct a fr
Iteru [2.4K]

According to Sturge's rule, number of classes or bins recommended to construct a frequency distribution is k ≈ 7

Sturge's Rule: There are no hard and fast guidelines for the size of a class interval or bin when building a frequency distribution table. However, Sturge's rule offers advice on how many intervals one can make if one is genuinely unable to choose a class width. Sturge's rule advises that the class interval number be for a set of n observations.

Given,

n = 66

We know that,

According to Sturge's rule, the optimal number of class intervals can be determined by using the equation:

k=1+log_{2} n

Here, n is equal to 66 and by substituting the value to the equation we get:

k=1+log_{2} (66)

k = 7.0444

k ≈ 7

expeople1 [14]
This question calls for a fraction.  In a fraction, the numerator (top number) is the number of parts, while the denominator (bottom number) is the total number of parts.  One part is one glass of milk, and there are 12 parts total.  So, we get the answer 1/12.

Answer: 1/12
