makkiz [27]

Answer:

The Man needs to run at 9 mph

Step-by-step explanation:

Let M stand for the man's speed in mph. When the man

runs toward point A, the relative speed of the train with respect

to the man is the train's speed plus the man's speed (45 + M).

When he runs toward point B, the relative speed of the train is the

train's speed minus the man's speed (45 - M).

When he runs toward the train the distance he covers is 2 units.

When he runs in the direction of the train the distance he covers

is 3 units. We can now write that the ratio of the relative speed

of the train when he is running toward point A to the relative speed

of the train when he is running toward point B, is equal to the

inverse ratio of the two distance units or

(45 + M) 3

----------- = ---

(45 - M) 2

90+2 M=135-3 M

⇒5 M = 45

⇒ M = 9 mph

The Man needs to run at 9 mph

PLEASE HELP ME GUYS!!

Maru [420]

Answer:

$\frac{7}{3}$

Step-by-step explanation:

csc(Ф) is equivalent to the inverse of sin(Ф)

$csc = \frac{1}{sin}$

Since sin(Ф) = 3/7, the inverse of this would be 7/3

So, $csc = \frac{1}{\frac{3}{7} }=\frac{7}{3}$

Help Please What is the measure of ∠b?

aleksandrvk [35]

Solution :-

Here we can see that ∠b is vertically opposite to 68° angle and we know that vertically opposite angles are equal.

So , the measure of ∠ b will also be equal to 68° .

More to know :

Alternate Interior angles are equal.
Corresponding angles are equal.
Sum of co - interior angles is 180° .
Alternate exterior angles are equal.
Measure of angle of straight line is 180°.
Vertically opposite angles are equal.

A Niffler is a magical creature who loves to collect shiny objects and store them in their pouch, much like a kangaroo. The amou

Fudgin [204]

Answer:

Probability that a Niffler can hold more than 32 pounds of shiny objects in their pouch is 0.1515.

Step-by-step explanation:

We are given that the amount a Niffler can hold in their pouch is approximately normally distributed with a mean of 25 pounds of shiny objects and a standard deviation of 6.8 pounds.

Let X = amount a Niffler can hold in their pouch

So, X ~ Normal( $\mu=25,\sigma^{2} =6.8^{2}$ )

The z score probability distribution for normal distribution is given by;

Z = $\frac{X-\mu}{\sigma}$ ~ N(0,1)

where, $\mu$ = population mean = 25 pounds

$\sigma$ = standard deviation = 6.8 pounds

Now, the probability that a Niffler can hold more than 32 pounds of shiny objects in their pouch is given by = P(X > 32 pounds)

P(X > 32 pounds) = P( $\frac{X-\mu}{\sigma}$ > $\frac{32-25}{6.8}$ ) = P(Z > 1.03) = 1 - P(Z $\leq$ 1.03)

= 1 - 0.8485 = 0.1515

The above probability is calculated by looking at the value of x = 1.03 in the z table which has an area of 0.8485.

Hence, the probability that a Niffler can hold more than 32 pounds of shiny objects in their pouch is 0.1515.
