kyle has 105 baseball cards and must give 2/5 of his cards away. how many cards will kyle give away? what fraction of his cards does he have left?

Answer:

5+10+6=21

4/21 = ___

Step-by-step explanation:

The probability that 4 randomly selected balls are all green will be;

"4/21 ".

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

Given:

Number of white balls = 5

Number of red balls = 10

Number of green balls = 6

The Total number of balls = 21

Therefore, The probability that 4 randomly selected balls are all green will be;

= 4/21

Given that:

Population Mean wage (m) = $24.57

a. State the null hypotheses we should use to test whether the population mean hourly wage in the manufacturing industry differs from the population mean hourly wage in the goods-producing industries.

The Null hypothesis : μ = 24.57

1 State the alternative hypotheses we should use to test whether the population mean hourly wage in the manufacturing industry differs from the population mean hourly wage in the goods-producing industries.

Alternative hypothesis : μ ≠ 24.57

1 b. Suppose a sample of 30 employees from the manufacturing industry showed a sample mean of $23.89 per hour. Assume a population standard deviation of $2.40 per hour and compute the p-value.

Sample size (n) = 30

Sample mean (Sm) = 23.89

Population standard deviation (σ) = 2.40

Obtaining Z:

Z = (Sm - m) / σ/√n

Z = (23.89 - 24.57) / 2.40/√30

Z = - 0.68 / 0.4381780

Z = - 1.5518805

Using the online p value calculator from Zscore

P value = 0.121142

The solution for the given system of equations as per linear and quadratic equation is (x, y) = (1, 2).

"A linear equation is an equation in which the highest power of the variable is always 1."

"A quadratic equation is an equation in which the highest power of the variable is always 2."

Given two linear equations are:

y = 5x – 3                        (1)  

y = x² + 3x – 2                (2)

Therefore, combining the two equations, we get:

5x - 3 = x² + 3x - 2

⇒ x² - 5x +3x - 2 + 3 = 0

⇒ x² - 2x + 1 = 0

⇒ (x)² - 2 × x × 1 + (1)² = 0

⇒ (x - 1)² = 0

⇒ (x - 1) = 0

⇒ x = 1

Now substituting the value of 'x' in the equation (1), we get:

y = 5 × 1 - 3

⇒ y = 2

Therefore, by solving the given two equations, we get: x = 1, y = 2.

Step-by-step explanation:

29x - 3 + 15x + 7 = 180° because these two angles are supplementary

if we add like terms

44x + 4 = 180

44x = 176 divide both sides by 44

x = 4

29x - 3 = 13y - 17 because alternate exterior angles has same measurement

since we found the value of x let's rewrite the equation

4 × 29 - 3 = 13y - 17

113 = 13y - 17

130 = 13y divide both sides by 13

Answer:

The third angle is 128°.

Step-by-step explanation:

We need to remember that the sum of the 3 angles of a triangle is 180°, hence if we have 2 angles, the third angle is:

[tex] 180 = \alpha + \beta + \theta [/tex]

[tex] 180 = 12 + 40 + \theta [/tex]

[tex] \theta = 180 - 52 [/tex]

[tex] \theta = 128 [/tex]

Therefore, the third angle is 128°.

x = 76 children's tickets sold

Step-by-step explanation:

Let x = the number of children's tickets sold

Let y = the number of adult tickets sold

x + y = 131

5.5x + 9.8y = 957    Solve the first equation for y

y = 131 - x        Multiply the second equation by 10

55x +98y = 9570     Substitute the above equation into this one.

55x + 98(131-x) = 9570   Use the distributive property

55x + 12838 - 98x = 9570   Solve the equation

-43x = -3268

x= 76 children's tickets sold

Answer: 88.56

Step-by-step explanation:

Given that:

Mean score (m) = 80.1

Standard deviation (s) = 7.2

Minimum score required to score A grade =?

A= Top 12% of scores

Zscore corresponding to top 12% = bottom 88%

Zscore = 1.175

Zscore = (x - mean) / s

1.175 = (x - 80.1) / 7.2

1.175 * 7.2 = x - 80.1

Step-by-step explanation:

Sabendo que 119 268 916 é divisível por 13, o número 119 268 903 também é divisível por 13.

Isso ocorre porque a diferença entre um múltiplo de um número e o próximo múltiplo de um número é esse próprio número.

Portanto, para encontrar outros múltiplos que são divisíveis por 13 dado o resultado na pergunta, podemos adicionar múltiplos menores de 13 ou subtrair múltiplos menores de 13 do número.

O que estamos dizendo é que o número - 13 ou mesmo -26 ou +39 daria outro múltiplo de 13. O que estamos dizendo é que chegaremos a um número que é divisível por 13 do outro número dado que o número que estamos adicionando ou subtrair do número é um múltiplo de 13.

Agora vamos verificar as opções, podemos ver que a diferença entre o número e a opção é 13 que, claro, é um múltiplo de 13.

Esta é a razão pela qual o número é a nossa resposta.
