Others have shown that it's possible to switch on a number of genes that reprogram adult cells to look and function like pluripotent embryonic stem cells

avanturin [10]

Answer:

The correct answer is "1668". A further solution is provided below.

Step-by-step explanation:

According to the question,

Estimated proportion,

\hat{p} = \frac{574}{1007}

  =0.57

Margin of error,

E = 0.02

Level of confidence,

= 90%

= 0.90

Critical value,

Z_{0.10}=1.65

Now,

⇒  0.02=1.65\times \sqrt{\frac{0.57\times 0.43}{n} }

 0.0004=2.7225\times \frac{0.2451}{n}

         n=\frac{2.7225\times 0.2451}{0.0004}

             =1668.21

or,

         n \simeq 1668

Carrots sell for $2.10 per pound, and crackers sell for $2.90 per pound. Glen bought some carrots and some crackers. The total w
musickatia [10]
The answer is
carrots - 0.8 pounds
crackers - 1.5 pounds


x - the weight of carrots
y - the weight of crackers
<span>The total weight was 2.3 pounds: x + y = 2.3
</span>
Carrots sell for $2.10 per pound: 2.10x
<span>Crackers sell for $2.90 per pound: 2.90y
</span><span>The total cost was $6.03: 2.10x + 2.90y = 6.03

</span>x + y = 2.3
2.10x + 2.90y = 6.03
_________
x = 2.3 - y
2.10x + 2.90y = 6.03
_________
2.10(2.3 - y) + 2.90y = 6.03
4.83 - 2.10y + 2.90y = 6.03
4.83 + 0.80y = 6.03
0.80y = 6.03 - 4.83
0.80y = 1.20
y = 1.20y : 0.80
y = 1.5 pounds

x = 2.3 - y = 2.3 - 1.5
x = 0.8 pounds

Give the line that is parallel to the line y=-5x-2 and goes through (3,-9)
igor_vitrenko [27]

Answer: I don’t think there is such a line. A Line that passes through the point (3,-9) must have a positive slope, unlike the line y=-5x-2, which has a negative slope. If a line where to go through (3,-9), is would intersect the line you presented.
