Probability = # of positive events / # of all possible events

As the event B restricts the number of consecutive cards that result in a positive outcome (only consecutive face cards), it means that the numerador of the formula to find the probability is smaller, while the denominator remains unchanged.

That means that the probabilty calculated for the event A is greater than the probability of the event B.

So, the answer is that the event A is more likely than event B.

When purchasing bulk orders of​ batteries, a toy manufacturer uses this acceptance sampling​ plan: randomly select and test 5858
Andreyy89
We use the binomial distribution:
P _{a}= \sum^c_d_=_0  \frac{n!}{d!(n-d)!} p^d (1-p)^n^-^d
In this formula, <em>c</em> is the acceptable number of defectives; <em>n</em> is the sample size; <em>p</em> is the fraction of defectives in the population.  Our <em>c</em> is 2; <em>n</em> is 58; and <em /><em>p</em> is 0.11.  Once we evaluate that summation, we get 0.0388.  This has a 3.88% chance of being accepted.  Since this is such a low chance, we can expect many of the shipments like this to be rejected.

Heather left the hospital and drove toward the desert at an average speed of 35 km/h. Danielle left sometime later driving in th
elena55 [62]

Answer:

Danielle drove 3 hours

Step-by-step explanation:

Suppose Heather moved in the x direction.

Then Danielle moved in the opposite direction, that is, she moved in the -x direction.

Let's call V_1, x_1, t_1 at the speed, distance and time that I code Heather

Let's call V_2, x_2, t_2 at the speed, distance and time Danielle codes.

Observe the following diagram:

(x) Heather <------ x_1 --------- hospital ---------- x_2 -----------> Danielle (-x)

So:

V_1 = 35\ km/h

t_1 = 4\ h

V_2 = 50\ km/h

We know that after 4 hours the distance between Heather and Danielle was 290 km.

That is to say:

x_2 + x_1 = 290\ km/h

We know that x_1= v_1t_1

x_1 = 35(4)

x_1 = 140\ km

We already know x_1, the distance from the hospital to Heather, so we can find x_2 and thus know t_2

So:

x_2 = 290 - 140\\\\x_2 = 150\ km

Then:

t_2 = \frac{x_2}{v_2}\\\\t_2 = \frac{150}{50}\\\\t_2 = 3\ h

Graph the function f(x)=4x^2+ 3x - 1
Marizza181 [45]

Step-by-step explanation:

The graph of a quadratic function is a U-shaped curve called a parabola. One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value. In either case, the vertex is a turning point on the graph. The graph is also symmetric with a vertical line drawn through the vertex, called the axis of symmetry.

Graph of a parabola showing where the x and y intercepts, vertex, and axis of symmetry are.

The

y

-intercept is the point at which the parabola crosses the

y

-axis. The

x

-intercepts are the points at which the parabola crosses the

x

-axis. If they exist, the

x

-intercepts represent the zeros, or roots, of the quadratic function, the values of

x

at which

y

=

0
