Answer:

x = 13

Step-by-step explanation:

Use pythagorean theorem since you have a right angle. So $c^{2} = a^{2} + b^{2}$

so in this case $c^{2} = 5^{2} + 12^{2}$ so c = $\sqrt{25+144}$ and c = $\sqrt{169}$ so c = 13

Which scatterplot has a correlation coefficient closest to r = –1?

UNO [17]

A coefficient of r = -1 is a negative so the dots would move downward as they move to the right ( higher dots are on the left side, lower dots on the right side. As the coefficient gets closer to -1 the dots form more of a straight line then being scattered across the graph.

The last graph, which is marked with the blue dot is the correct one.

The Lone Star Shipping Company charges $14 plus $2 a pound to ship an overnight package. Discount Shipping Company charges $20 p

Ymorist [56]

Answer:

12 pound

Step-by-step explanation:

Let $x$ be the weight of the package.

For Lone Star Shipping, the cost will be:

$2x + 14$

For Discount Shipping Company, the cost will be:

$1.5x + 20$

We hence equate these two expressions equal to each other, since the cost should be same.

$2x + 14 = 1.5x + 20 \\2x - 1.5x = 20 -14\\0.5x = 6\\x = 6 \div 0.5\\x = 12$

Melanie has a bag that contains orange chews, cherry chews, and peach chews. She performs an experiment. Melanie randomly remove

adoni [48]

Answer:

0.30

Step-by-step explanation:

Given that:

Total number of trials = 61

Number of orange chews = 38

Number of cherry chews = 5

Number of peach chews = 18

Probability that next chew removed will be a peach chew ;

This is an experimental probability problem ;

Using the relation :

Experimental probability of A;

Number of successes (A) / total number of trials

Hence, Probability that next chew removed will be a peach chew ;

Experimental probability of peach chew :

Number of trails = 61 ; number of successes (peach chew) = 18

P(peach chew) = 18 / 61

P( peach chew) = 0.2950819

= 0.30 ( nearest hundredth)
