Savatey [412]3 years ago
7 0

Answer:

x = \sqrt{15} / 3

Step-by-step explanation:

3x² - 10 = -5

3x² = 5

x² = 5/3

x = \sqrt{5} / \sqrt{3}

Multiply both numerator and denominator by \sqrt{3}

x = \sqrt{15} / 3

Tell whether each equation represents a direct proportion. If so, identify the
sveticcg [70]

Answer:

Step-by-step explanation:

1. 0.4y = x is a direct proportion.  It'd be more appropriate to write this as

   y =  x / 0.4, or y = 2.5x, in which case 2.5 is the constant of proportionality.

2. x = 1 - 2y is not a direct proportion because of the offset (1).  A line representing a direct proportion must go through the origin (0, 0); this particular line does not do that.

A box is filled with 2 blue cards, 4 brown cards, and 6 yellow cards. A card is chosen at random from a box. What is the probabi
Finger [1]

Answer:

Therefore the probability that the card is not brown is \frac12.

Step-by-step explanation:

Probability: Probability is the ratio of the favorable outcome to the total outcome.

Probability =\frac{\textrm{Favorable outcome}}{\textrm {Total outcome}}

Given that, a box contains  2 cards blue in color , 4 cards brown in color and 6 cards yellow in color.

Total number of cards= (2+4+6)=12

∴P(getting a brown card)

=\frac{\textrm{No. of brown card}}{\textrm{Total no. of card}}

=\frac{6}{12}

=\frac12

∴P(not getting a brown card)

=1 - P(getting a brown card)

=1-\frac12

=\frac12

Therefore the probability that the card is not brown is \frac12.
