A basketball player is 6ft 8in tall. A model of the basketball player is 5 inches tall. What is the scale factor

Answers

Answer:

1 ft. = 16 in.

Step-by-step explanation:

6 ft. 8 in. is 80 in.

then you would divide 80 by 5 to get 16.

not sure what scale factor you were looking for, so i did ft. to in.

not 100% sure though

best of luck!

A project manager can interpret several things from data displayed in a histogram. If something unusual is happening, the histogram might be ___________. a. Flat b. Skewed c. Bell-shaped d. S-shaped

Answers

Answer:

Skewed

Step-by-step explanation:

A project manager can interpret several things in a histogram. If something unusual happening, the histogram is said to Skewed. When the histogram is Skewed it means that many of the values of the graph are falling on only one side of the mean. It can be either on left side( left skewed) or on the right side called right skewed

Final answer:

The like radical to the expression 3√5 is y√5, as both expressions have the square root index and the same radicand, which is 5.

Explanation:

The student is asking which radical expression is like the radical 3√5. Like radicals have the same index and radicand. The index is the degree of the root, and the radicand is the number under the radical sign. The expression 3√5 means 3 times the square root of 5, or in exponential form, 3 × 51/2. The like radical for 3√5 would also need to have a square root (index of 2) and the same radicand (5). Therefore, the like radical to 3√5 from the options provided would be y√5 because it has the same index (2) and radicand (5), only with a different coefficient (y instead of 3).

Additionally, expressing radicals as fractional exponents helps to identify like radicals. For example, using the property x² = √x we can understand that if we have the same base and exponent, we can consider the expressions to be like radicals. Hence, in this case, since both 3 and y are just coefficients, the root parts √5 are the same, making them like radicals.
