Answer:

Step-by-step explanation: i dont know but i still can help i think its answer The graph that best represent the solution set of y > 3x - 4 is D. The inequality is as follows: y > 3x - 4. lets find y when x = 0.

liraira [26]

Answer:

68 bicycles.

Step-by-step explanation:

Let there be x bicycles, then there are (93 - x) tricycles.

From the given values:

2x + 3(93 - x) = 211

2x + 279 - 3x = 211

-x = 211 - 279 = -68

x = -68/-1 = 68.

fenix001 [56]

Answer:

The lower bound of a 99% C.I for the proportion of defectives = 0.422

Step-by-step explanation:

From the given information:

The point estimate = sample proportion $\hat p$

$\hat p = \dfrac{x}{n}$

$\hat p = \dfrac{55}{100}$

$\hat p$ = 0.55

At Confidence interval of 99%, the level of significance = 1 - 0.99

= 0.01

$Z_{\alpha/2} =Z_{0.01/2} \\ \\ = Z_{0.005} = 2.576$

Then the margin of error $E = Z_{\alpha/2} \times \sqrt{\dfrac{\hat p(1-\hat p)}{n}}$

$E = 2.576 \times \sqrt{\dfrac{0.55(1-0.55)}{100}}$

$E = 2.576 \times \sqrt{\dfrac{0.2475}{100}}$

$E = 2.576 \times0.04975$

E = 0.128156

E ≅ 0.128

At 99% C.I for the population proportion p is: $\hat p - E$

= 0.55 - 0.128

= 0.422

Thus, the lower bound of a 99% C.I for the proportion of defectives = 0.422

If a right triangle has its two other angles labeled as 3x + 10 and 5x + 16, find the

irakobra [83]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Sum of the interior angles of any triangle equal 180 degrees .

Thus ;

$(3x + 10) + (5x + 16) + 90 = 180 \\$

Subtract sides 90

$(3x + 10) + (5x + 16) + 90 - 90 = 180 - 90 \\$

Simplification

$(3x + 10) + (5x + 16) = 90$

$3x + 10 + 5x + 16 = 90$

Collect like terms

$3x + 5x + 10 + 16 = 90$

$8x + 26 = 90$

Subtract sides 26

$8x + 26 - 26 = 90 - 26$

$8x = 64$

Divide sides by 8

$\frac{8x}{8} = \frac{64}{8} \\$

$x = 8$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

So ;

The angle marked as 3x + 10 would measure 34° degrees.

$3(8) + 10 = 24 + 10 = 34$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

And ;

The angle marked as 5x + 16 would measure 56° degrees.

$5(8) + 16 = 40 + 16 = 56$
