Answer:

p = 2, q = 3.

Step-by-step explanation:

A perfect cube is in the form $a^{3}$ .

$\frac{6.54.p}{q} = \frac{324.p}{q} = \frac{2^{2}.3^{4}.p }{q}$

To make this fraction a perfect cube, we need to increase the exponent of 2 to 3 and decrease the exponent of 3 to 3.

Conclusion: $p = 2, q = 3$ .

Question 2

svetoff [14.1K]

Answer:

A: 37/41

Step-by-step explanation:

We can observe that:

The difference of the second and third numbers is equal to 17
The difference of the first and fourth numbers is equal to 13

Therefore the missing pair will be:

20+17 = 37 and 28 + 13 = 41

Correct choice is A

Use the normal distribution of SAT critical reading scores for which the mean is 502 and the standard deviation is 116. Assume t

PSYCHO15rus [73]

Answer:

(a) 93.19%

(b) 267.3

Step-by-step explanation:

The population mean and standard deviation are given as 502 and 116 respectively.

Consider, X be the random variable that shows the SAT critical reading score is normally distributed.

(a) The percent of the SAT verbal scores are less than 675 can be calculated as:

$P(X$

Thus, the required percentage is 93.19%

(b)

The number of SAT verbal scores that are expected to be greater than 575 can be calculated as:

$P(X>575)=P(\frac{x-502}{116}>\frac{575-502}{116}\\P(X>575)=P(Z>\frac{575-502}{116})\\P(X>575)=P(Z>0.6293)\\P(X>575)=0.2673$

So,

Out of 1000 randomly selected SAT verbal scores, 1000(0.2673) = 267.3 are expected to have greater than 575.

Show that x = -2 is a solution of 3x² + 13x + 14 = 0

Oliga [24]

Answer:

x= -2 is correct answer

Step-by-step explanation:

3(-2×-2)+13(-2)+14=0

3(4)+13(-2)+14=0

12+(-26)+14=0

12-26+14=0

12+14-26=0

26-26=0

0=0
