Answer:

The product of (3.7 × 10⁴) and 2 is (7.4 × 10⁴). Therefore the correct option is A.

Step-by-step explanation:

We need to find the product of (3.7 × 10⁴) and 2.

$Product=(3.7\times 10^4)\cdot 2$

It can be written as

$Product=3.7\cdot 2\times 10^4$

On simplification we get

$Product=7.4\times 10^4$

The product of (3.7 × 10⁴) and 2 is (7.4 × 10⁴). Therefore the correct option is A.

Karen wants to advertise how many chocolate chips are in each Big Chip cookie at her bakery. She randomly selects a sample of 60

Umnica [9.8K]

Sample mean : \overline{x}=10.6x=10.6

Standard deviation : s=1.7s=1.7

Significance level : \alpha:1-0.95=0.05α:1−0.95=0.05

Critical value : z_{\alpha/2}=1.96

Hence the 95% confidence interval for the number of chocolate chips per cookie for big chip cookies= (10.1989,\ 11.0011)(10.1989, 11.0011)

a cylindrical well has a radius of 10 feet and a height of 15 feet what volume of water will it take to fill in the well

vampirchik [111]

Volume of water will it take to fill in the well is 4710 cubic feet

<h3>Solution:</h3>

Given that a cylindrical well has a radius of 10 feet

Height of cylindrical well = 15 feet

To find: volume of water will it take to fill in the well

Since, the well is in the form of cylinder, This means that we need to find the volume of cylindrical well

The volume of cylinder is given as:

$\text { Volume of water in the well }=\pi r^{2} h$

Where "r" is the radius and "h" is the height of cylinder

Substituting the given values we get,

$\begin{array}{l}{\text { Volume of water in the well }=(3.14) \times(10)^{2} \times(15)} \\\\ {=(3.14) \times(1500)=4710}\end{array}$

$\text { Volume of water in the well }=4710 \text { feet }^{3}$

Hence, the amount of water that can be stored in the well is 4710 cubic feet

Loretta places 20 red tiles in a bag. How many blue tiles must be added to the bag to make the probability of randomly drawing a

Galina-37 [17]

Answer:

If the number of blue tiles in the bag is 180, then the probability of randomly drawing a red tile equal to 1/10.

Step-by-step explanation:

Total number of red tiles in a bag = 20

Let us assume the number of blue tiles in a bag = p

So, the total number of tiles in a bag = Red Tiles + Blue tiles

= 20 + p

Now, let us find the probability of drawing a red tile:

$\textrm{The probability of drawing a red tile} = \frac{\textrm{Total Number of red tiles}}{\textrm{Total Tiles}}\\= \frac{20}{20 + p}$

But, here the probability of drawing a red tile = 1/10

$\implies \frac{1}{10} = \frac{20}{20+p} \\\implies 20 + p = 200\\\implies p = 200- 20 = 180$

or, p = 180

Hence, if the number of blue tiles in the bag = 180, then the P Picking out a red tile ) is 1/10.
