What is the answer to number 4

Testing the hypothesis, it is found that the p-value of the test is 0.017 < 0.05, which means that we can conclude that the red shirt increases his chances of winning.

At the null hypothesis, we test if the proportion is of 40%, that is:

[tex]H_0: p = 0.4[/tex]

At the alternative hypothesis, we test if the proportion is greater than 40%, that is:

[tex]H_1: p > 0.4[/tex]

The test statistic is:

[tex]Z = \frac{X - p}{s}[/tex]

In which:

[tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex]

With n as the sample size.

In this problem:

[tex]s = \sqrt{\frac{0.4(0.6)}{3}} = 0.283[/tex]

The value of the test statistic is:

[tex]Z = \frac{X - p}{s}[/tex]

[tex]Z = \frac{1 - 0.4}{0.283}[/tex]

[tex]Z = 2.12[/tex]

The p-value is the probability of finding a sample proportion of 1 or "above", which is 1 subtracted by the p-value of Z = 2.12.

The p-value of the test is 0.017 < 0.05, which means that we can conclude that the red shirt increases his chances of winning.

Answer:

y = 1/2x + 3

Step-by-step explanation:

First we find the slope:

(y2 - y1)/(x2 - x1) =

3-0 / 0 + 6

3/6 = 1/2

then the y intercept is 0,3 so we add 3

y = 1/2x +3

Answer:

32500 per year

Step-by-step explanation:

multiply 50 weeks to 50 hours to get how many hours does 50 week have then multiply the outcome result of the two to the $13 to get the money he/she would earn in a year.

The question is an illustration of inequalities.

The inequality that represents Lashonda's amount of exercise is: [tex]\mathbf{t \ge 50}[/tex]

The given parameter is:

[tex]\mathbf{Minutes = At\ least\ 50}[/tex]

In inequality, at least means greater than or equal to.

So, the above equation becomes:

[tex]\mathbf{Minutes \ge 50}[/tex]

From the question, we understand that the number of minutes should be represented with t.

So, we have:

[tex]\mathbf{t \ge 50}[/tex]

Hence, the inequality is: [tex]\mathbf{t \ge 50}[/tex]

Answer: i needed pointsss srry

Step-by-step explanation:

Queremos ver cuantas combinaciones diferentes se pueden hacer con una letra del abecedario y los números 8 y 14.

La respuesta es:

Hay 162 combinaciones diferentes.

Primero dejemos la letra fija, asumamos que queremos ver las combinaciones entre la letra A, el número 8, y el número 14.

Tenemos 3 elementos, entonces el número de combinaciones será solo 3 factorial, o:

combinaciones = 3! = 3*2*1 = 6

Hay 6 combinaciones diferentes de esos 3 elementos.

Ahora recordamos que ademas de A hay 26 opciones más, entonces la letra tiene un total de 27 permutaciones posibles. Es decir, el número total de combinaciones va a ser 27 veces lo que obtuvimos arriba:

Total de combinaciones = 6*27 = 162

Hay 162 combinaciones diferentes.

Answer:

Yes, because momentum is conserved in all inelastic collisions which all car accidents are

Step-by-step explanation:

What is law of conservation of momentum?

It states that In a equilibrium the initial momentum is equal to to the final momentum of the body

Or

[tex]\\ \sf\longmapsto \Delta P=P[/tex]

Answer:

• Yes, because momentum is conserved in all collisions.

Step-by-step explanation:

→ Elastic collision, inelastic collision and perfectly inelastic collision, linear momentum is conserved assuming no external forces acting on the system.

In elastic collision

[tex] \dashrightarrow \: { \tt{m _{1}u _{1} + m _{2} u_{2} = m_{1}v_{1} + m_{2}v_{2}}} \\ [/tex]

In inelastic collision

[tex] \dashrightarrow \: { \tt{m_{1}u_{1} + m_{2}u_{2} = (m_{1} + m_{2})v}}[/tex]
