Talia tossed a penny many times. She got 30 heads and 70 tails. She said the experimental probability of getting heads was 30 70

-BARSIC- [3]

Answer:

The experimental probability of landing on heads is 0.3

Step-by-step explanation:

We are given the following in the question:

Number of heads = 30

Number of tails = 70

Talia said the probability of getting heads is $\frac{30}{70}$ .

She evaluated the wrong probability.

She did not considered total number of trials in the experiment.

Formula for probability:

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

Probability of heads =

$P(H) = \dfrac{30}{30+70} = \dfrac{30}{100} =0.3$

The experimental probability of landing on heads is 0.3

If the end behavior is increasing on the left and decreasing on the right, which statement must be true about the function?

tatiyna

Answer:

The degree is even and the leading coefficient is negative.

Step-by-step explanation:

Given that the end behavior of the function is decreasing on the right, this means that x approaches positive infinity as y approaches negative infinity, which tells us that our leading coefficient is negative. Additionally, since our function is increasing on the left, then our function is even, which is symmetric to the origin.

A train leaves boston and travels toward its destination at a speed of 60 mph. One hour later, an express train leaves Boston an

Margarita [4]

Taking into account the supplied speeds, Boston is from the destination to:

240 miles

<h3>Calculation of the distance between Boston and Place of Destination</h3>

To identify the distance between Boston and the destination of the trains, it must be remembered that the <u>speed</u> mentioned for each one is a reference to the distance traveled per hour, therefore, after each hour, each train will travel :

Regular train: 60 miles
Express train: 80 miles

According to the information given, when the express train leaves, the regular train has a 60-mile lead, which is getting shorter hour by hour because the express train travels 20 miles per hour more than the normal train.

Therefore, in <u>three hours</u>, the express train would catch up with the regular train, calculating the distance thanks to the speed formula:

$Speed =\frac{Distance}{Time}$

And clearing the distance:

$Distance=Speed*Time$

$Distance=80\frac{miles}{hour}*3hours$

$Distance=240miles$

Therefore, the destination would be <u>240 miles</u> from Boston, which would take four hours by regular train and three hours by express train.
