What are the factors of 2x2 + 3x – 54? Select two options.

Darya [45]

Hello there,

The equation that we have to factor is as follows:

2x² + 3x - 54

In order to factor this we first multiply (-54) by 2 and try to find two factor pairs that can be add up to 3.

For this we would use 12 * -9 which gives you -108 when multiplied and when added you would get 3.

2x² + 12x - 9x -54

2x(x + 6) -9(x +6)

(2x - 9) (x + 6)

Now the factor pairs would be: (2x - 9)(x + 6)

Hope I helped,

48% of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually

oksian1 [2.3K]

Answer:

There is no sufficient evidence to support the executive claim

Step-by-step explanation:

From the question we are told that

The population proportion is $p = 0.48$

The sample proportion is $\r p = 0.45$

The sample size is $n = 300$

The level of significance is $\alpha = 0.02$

The null hypothesis is $H_o : p= 0.48$

The alternative hypothesis is $H_a : p \ne 0.48$

Generally the test statistics is mathematically evaluated as

$t = \frac{\r p - p }{ \sqrt{ \frac{p(1 - p )}{n} } }$

=> $t = \frac{0.45 - 0.48 }{ \sqrt{ \frac{0.48 (1 - 0.48 )}{300} } }$

=> $t = -1.04$

The p-value is mathematically represented as

$p-value = 2P(z > |-1.04|)$

Form the z-table

$P(z > |-1.04|) = 0.15$

=> $p-value = 2 * 0.15$

=> $p-value = 0.3$

Given that $p-value > \alpha$ we fail to reject the null hypothesis

Hence we can conclude that there is no sufficient evidence to support the executive claim

5 1/2 - 3/8

Make 5 1/2 into a improper fraction

5 1/2=11/2. Mutiply the whole number with the denominator. 5*2= 10. Add 10 with the numerator. 10+1= 11

11/2-3/8.

Find the common denominator for 11/2 which is 8. Mutiply by 4

11(4)/2(4)= 44/8

44/8-3/8= 41/8= 5 1/8

Answer: 41/8 or 5 1/8
