Answer:

a. $\bold{45000\times \:10^7}$
b. $\bold{3500}$

Step-by-step explanation:

a. $\left(5\times \:10^3\right)\left(9\times \:10^7\right)$

$5\times 10^3 = 5000\\\\5000\times \:9\times \:10^7$

$\mathrm{Multiply\:the\:numbers:}\:5000\times \:9=45000$

$=45000\times \:10^7$

b. $\left(7\times 10^5\right)\div \left(2\times 10^2\right)$

$\left(7\times 10^5\right)\div \left(2\times 10^2\right)=\frac{7\times \:10^5}{2\times \:10^2}$

$\frac{10^5}{10^2} = 10^3$

$\frac{7\times \:10^3}{2}$

$\mathrm{Factor}\:\: 10^3 : 2^3\times5^3$

$\frac{7\times \:2^3\times \:5^3}{2}$

$\frac{2^3}{2}=2^2$

$7\times \:2^2\times \:5^3=3500$

Kayla wants to represent "18 divided by the sum of 3 and 3". She writes 8/(3x3) . Is Kayla's expression correct? Explain using c

Naya [18.7K]

no it is not correct. 18 divided by the sum of 3 and 3 equals 18 ÷ (3+3)

"sum of 3 and 3 " means 3+3 therefore 8/(3x3) = 8/9 and is completely different from the equation desired to be represented.

At Joe's Grocery, you can buy hot dogs only in packages of 4 or packages of 7. As a result, you can't buy exactly 9 hot dogs sin

Inessa05 [86]

Answer:

Step-by-step explanation:

Hot Dog packages

4 = 2 *2

7 = 1 * 7

To determine, the largest possible number of hot dogs that you can't get exactly by buying these hot dogs is to determine the LCM ( lowest common multiple of 4 and 7 ) and add 1 to it

LCM of 4 and 7 = 1 * 2 * 2 * 7 = 28

Highest number that combining 7 and 4 packages can't give = 28 + 1 = 29

In testing the hypotheses H 0 colon space mu space equals space 800 space v s. space H 1 colon space mu not equal to space 800,

steposvetlana [31]

Answer:

The p-value is 0.0802.

Step-by-step explanation:

The hypothesis for a test is defined as:

H₀: μ = 800 vs. Hₐ: μ ≠ 800

A two tailed test for the population mean can be performed using a z-test or a t-test.

A z-test is used if the data provided has information related to the population standard deviation and the sample size is large, i.e. n > 30.

And if the population standard deviation is not known and the sample size is small, then the t-test will be used.

Since there is no information about either the population standard deviation or the sample size, assume that z-test is used.

The test statistic value is:

z = 1.75

Compute the p-value of the test as follows:

$p-value=2\times P(Z>z)\\$

$=2\times (1-0.9599)\\=2\times 0.0401\\=0.0802$

*Use a z-table for the probability.

Thus, the p-value is 0.0802.
