mrs_skeptik [129]

Answer:

$\frac{6}{49}$

Step-by-step explanation:

GIVEN: There are two boxes. in the first box there are $7$ cards numbered from $1$ to $7$ the second box also contains $7$ cards from $1-7$ pick one card from each box.

TO FIND: probability that the sum of the two two cards is at least $12$ .

SOLUTION:

sample case such that sum of cards is $12$ : $(5,7),(7,5),(6,6)$

sample case such that sum of cards is $13$ : $(7,6),(6,7)$

sample case such that sum of cards is $14$ : $(7,7)$

Total sample case such that sum is atleast $12$ $=6$

Total sample cases $=49$

probability that the sum of the two two cards is at least $12$ $=\frac{\text{sample case in which sum is atleast 12}}{\text{total sample cases}}$

$=\frac{6}{49}$

probability that the sum of the two two cards is at least $12$ is $\frac{6}{49}$

52 is what percent of 260

Nataly_w [17]

"is" means =
"what percent" can represent x
"of" is multiplying

so 52 = 260x
so divide 260 by both sides so
x = 52/260 = 0.2
and 0.2 = 20%

A rectangular swimming pool measures 50 meters in length and 25 meters in width. If the length in the scale drawing is 10 cm, wh

mash [69]

Answer:

The 25 m width of the actual swimming pool in the scale drawing is 5 cm

Step-by-step explanation:

The dimensions of the actual swimming pool given are

Length = 50 meters

Width = 25 meters

The length of the swimming pool on the scale drawing = 10 cm

The scale of the scale drawing is therefore;

10 cm on the scale drawing is equivalent to 50 meters of the actual swimming pool

Which gives;

10 cm:50 m

However, 50 m = 5,000 cm, therefore;

10 cm:5,000 cm or 10 : 5,000

Which is 10 to 5000 or 10/10 to 5000/10 = 1 to 500

The scale of the scale drawing is 1 to 500

or 1 cm of the scale drawing = 5 meters of the actual swimming pool

Therefore, the width of 25 meters of the actual swimming pool can be given as follows;

5 m = 1 cm

1 m = 1 cm/5

25 m = 25× 1 m = 25 × 1 cm/5 = 5 cm

Therefore, the 25 m width of the actual swimming pool in the scale drawing = 5 cm.

HEEEEEEELLLPPPPPPPPP!!!!! PLEASEEEEEEEE

Klio2033 [76]

Answer:

a) $a_n=2(a_{n-1})$ , where $a_1=5$ .

b) $a_n=5(2)^{n-1}$

Step-by-step explanation:

The given sequence is

$5,10,20,40...$ .

The first term of the sequence is

$a_1=5$

The second term is $a_2=10$

The common ratio for this sequence can be determined using any two consecutive terms in the sequence.

Using the first two terms, the common ratio is

$r=\frac{a_2}{a_1}$

$\Rightarrow r=\frac{10}{5}=2$

a) The recursive rule is given by,

$a_n=r(a_{n-1})$

$a_n=2(a_{n-1})$ , where $a_1=5$ .

b) The explicit rule is given by $a_n=a_1r^{n-1}$

$\Rightarrow a_n=5(2)^{n-1}$
