The answer would be C. Because you would have to have the number of glue sticks on the same side of the fractions otherwise you won't get the right answer.

A group of adults and students went on a class trip to Washington, DC. The number of male students was 1 more than 7 times the n

algol [13]

Alright.
So let's say the number of adults is x.
Therefore, the number of boys is 7x + 1.
And then the total amount of girls is 3.5x + 0.5
So then:
x + 7x + 1 + 3.5x + 0.5 = 82
11.5x + 1.5 = 82
11.5x = 80.5
x = 7
So now we can figure out the number of male and female students.
Male students = 7x + 1
7*7 + 1
49 + 1
50
Male Students = 50
Female students = half of 50
50/2 = 25
Female Students = 25

1.The coordinates of the vertices of △RST are R(−4, −1) , S(−1, −1) , and T(−4, −2) .

Tju [1.3M]

RS points east; R'S' points north, so there has been a rotation 90° CCW.

After that rotation, point S would be at (1, -1). It is actually at (1, 1), so has been shifted 2 units upward.

A sequence that does the desired mapping is

c. rotation of 90° CCW about the origin
b. translation 2 units up

The weights for newborn babies is approximately normally distributed with a mean of 5.4 pounds and a standard deviation of 1.8 p

Mariana [72]

Answer:

You would expect 807 babies to weigh between 3 and 6 pounds.

Step-by-step explanation:

We are given that

Mean, $\mu=5.4$ pounds

Standard deviation, $\sigma=1.8$ pounds

n=1500

We have to find how many would you expect to weigh between 3 and 6 pounds.

The weights for newborn babies is approximately normally distributed.

Now,

$P(3$

$=P(-1.33$

$P(3$

$P(3$

$P(3$

Number of newborn babies expect to weigh between 3 and 6 pounds

= $1500\times 0.538=807$
