The greatest number of friends who can receive a necklace is 6. The reason why is because 6 is the greatest common factor of 72 and 42.

Each friend will have 12 blue beads and 7 red beads. If you divide 6 (GCF) with both numbers you get 12 and 7.

Hope this helps :3

Solving Exponential and Logarithmic Equation In exercise,solve for x or t.See example 5 and 6.
Natalija [7]

Answer:

x=3 , x=-3

Step-by-step explanation:

e^{lnx^2} -9= 0

Add 9 on both sides

e^{lnx^2}=9

To remove base 'e' we take ln on both sides

ln e^{lnx^2}=ln9

lnx^2=ln(9)

Both sides have ln , so we make the terms equal

x^2=9

Take square root on both sides

x=+-3

x=3 , x=-3

Surface area and volume of a regular triangular pyramid that has a base edge of 16 cm and a slant height of 15 cm
Schach [20]

Answer:

a) Surface area = 616 cm²

b) Volume = V = 1083 cm³

Step-by-step explanation:

Surface area and volume of a regular triangular pyramid that has a base edge of 16 cm and a slant height of 15 cm

a) Formula for surface area = Base area × 1/2(perimeter × slant height)

Base area = Base edge²

=( 16 cm)² = 256 cm²

Perimeter = Base edge × 3

= 16 cm × 3 = 48 cm

Hence:

Surface Area = 256 cm² + 1/2(48 × 15)

= 256 cm² + 360 cm²

= 616 cm²

b) Volume = 1/3 × Base area × Height

1082.758616785cm³

Approximately = 1083 cm³

David wants to complete a hypothesis test with the least amount of probability for error. If he sets the significance level to 1
Brrunno [24]

Answer:

He could increase the sample size

Step-by-step explanation:

In hypothesis testing, the error associated with the test is affected by a number of factors. The first factor is the level of significance, alpha. This is the probability of type 1 error. The probability of rejecting the null hypothesis when it is indeed true.

The second factor is the size of the sample used. The larger the sample, the smaller the error since the characteristics of the sample will be closer to those of the entire population on which inference is being made
