Answer: 49 flowers .

Step-by-step explanation:

Hi, to answer this question, first, we have to sum the number of flowers:

3 pink roses + 4 tulips = 7 flowers

She uses 7 flowers to fill each vase, so, to calculate how many flowers are used to fill 7 vases we simply multiply the number of flowers used to fill one vase (7) by the number of vases(7).

Mathematically speaking:

7 x7 =49 flowers

To find how many flowers of each type she uses to fill the 7 vases:

Pink roses: 3 x 7 = 21
Yellow tulips: 4 x 7 = 28

Nuetrik [128]

Answer:(0,5)

Step-by-step explanation:

Y-3=2(x+1)

Rewrite it

2(x+1)=y-3

Sub. 0 for xto find y

2=y-3

Y-3=2

Y=2+3

Y=5

5-3=2(x+1)

2=2x+2

2x+2=2

2x=-2+2

2x= 0

X=0

To check

5-3=2(0+1)

2=2(1)

2= 2

It checks

In a survey of a community, it was found that 55%

ella [17]

Answer:

The number of people who like winter season is 1000.

Step-by-step explanation:

Event event correspond to a set in the Venn diagram, and we use it to find the percentages.

I am going to say that:

Event A: Like summer season

Event B: Like winter season.

55% like summer season

This means that $P(A) = 0.55$

20% like winter season

This means that $P(B) = 0.2$

40% don't like both seasons

This means that 100% - 40% = 60% like at least one, which means that $P(A \cup B) = 0.6$

Proportion who like both:

This is $P(A \cap B)$ . The measures are related by the following equation:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

$P(A \cap B) = P(A) + P(B) - P(A \cup B)$

Using what we have

$P(A \cap B) = 0.55 + 0.2 - 0.6 = 0.15$

750 like both seasons.

This is 15% of the sample. So the total number of people is t, for which:

$0.15t = 750$

$t = \frac{750}{0.15}$

$t = 5000$

20% like winter season

Out of 5000. So

0.2*5000 = 1000

The number of people who like winter season is 1000.
