forsale [732]

Answer:

option (c) n = 201

Step-by-step explanation:

Data provided in the question:

Standard deviation, s = 5.5 ounce

Confidence level = 99%

Length of confidence interval = 2 ounces

Therefore,

margin of error, E = (Length of confidence interval ) ÷ 2

= 2 ÷ 2

= 1 ounce

Now,

E = \frac{zs}{\sqrt n}

here,

z = 2.58 for 99% confidence interval

n = sample size

thus,

1 = \frac{2.58\times5.5}{\sqrt n}

or

n = (2.58 × 5.5)²

or

n = 201.3561 ≈ 201

Hence,

option (c) n = 201

23) m 2 = 7x + 6<br>70°​
lakkis [162]

Answer:

∠2 = 55°

Step-by-step explanation:

Given that the triangle has 2 congruent sides then the triangle is isosceles.

Thus the 2 base angle are congruent, both equal to ∠2

The sum of the 3 angles in a triangle = 180

7x + 6 + 7x + 6 + 70 = 180, that is

14x + 82 = 180 ( subtract 82 from both sides )

14x = 98 ( divide both sides by 14 )

x = 7

Hence

∠2 = 7x + 6 = (7 × 7) + 6 = 49 + 6 = 55°

Help me please!!!!!!!!
pogonyaev

Answer:

1) 4

2) 1.5

3) 8

4) 1

5) 5

6) 9

Step-by-step explanation:

<h3>1)</h3><h3> √16</h3>

= √(4x4)

= √(4)²

<h3>= 4</h3>

<h3>2)</h3><h3>√2.25</h3>

= √(9/4)

= √(3x3)/(2x2)

= √(3)²/(2)²

= 3/2

<h3>= 1.5</h3>

<h3>3)</h3><h3>6² ÷ 9 x 2 </h3>

= 36 ÷ 9 x 2

= 36 x 1/9 x 2

= 36/9 x 2

= 12/3 x 2

= 4 x 2

<h3>= 8</h3>

<h3>4)</h3><h3>12-2 / 6+4</h3>

= 10/10

<h3>= 1</h3><h3 /><h3>5)</h3><h3>√(16+9)</h3>

= √(25)

= √(5x5)

= √(5)²

<h3>= 5</h3><h3 /><h3>6)</h3><h3>63 ÷ 3² + |2|</h3>

= 63 ÷ 9 + |2|

= 63/9 + |2|

= 21/3 + |2|

= 7 + |2|

<h3>= 9</h3>
