Answer:

7/10 or 70%.

Step-by-step explanation:

There is a total of 20 marbles in the bag.

There are 10 + 4 = 14 marbles which are not blue.

The required probability = 14/20

= 7/10.

Which sequence of transformations produces R’S’T’ from RST?

inn [45]

Answer:

A translation 2 units right and then a reflection over the x-axis

Step-by-step explanation:

The given vertices of ΔRST are R(0, 0), S(-2, 3), and T(-3, 1)

The vertices of triangle ΔR'S'T' are (2, 0), (0, -3), (-1, -1)

The points are plotted with the aid of MS Excel, and by observation, we have that the image of ΔRST is located on the other side of the x-axis with each coordinate on ΔR'S'T' shifted 2 units to the right of ΔRST

A translation of ΔRST 2 units right gives;

(0 + 2, 0) = (2, 0), (-2 + 2, 3) = (0, 3), and (-3 + 2, 1) = (-1, 1), to give;

(2, 0), (0, 3), and (-1, 1)

A reflection of the point (x, y) across the x-axis gives (x, -y)

A reflection of the above points across the x-axis gives;

(2, 0) reflected about x-axis → (2, 0) reflected about x-axis → (0, -3), and (-1, 1) reflected about x-axis → (-1, -1), which are the points of ΔR'S'T'

Therefore, the sequence of transformations that produces R'S'T' from RST are;

A translation 2 units right and then a reflection over the x-axis

PLS Help Asap! i will award brainliest On her way to her grandmother's house, Jackie traveled three times as many miles by train

nirvana33 [79]

Answer:

24 miles.

Step-by-step explanation:

Jackie traveled four times as many miles by bus as by foot. This means that the number of miles travelled by bus is 4 units, and the number of miles travelled by foot is 1 unit.

Jackie traveled three times as many miles by train as by bus. We know that the number of miles travelled by bus is 4 units, so the number of miles travelled by train is $4\times3=12$ units.

Total number of units: $12units+4units+1unit=17units$

$17units=34$

Divide 17:

$1 unit=2$

The number of miles travelled by train is 12 units:

$12units=2\times 12=24$

She travelled 24 miles by train.
