Answer:

1 over 18

Step-by-step explanation:

The spinner has 3 segments and he spun it 1 time. So, he has a 1 in 3 chance of landing on green.

There are 6 cards so he has a 1 and 6 chance of picking up the yellow card.

Multiply those and you have 1 over 18

Done!

A random sample of 100 recorded deaths in the United States during the past year showed an average life span of 71.8 years. Assu

Oliga [24]

Answer:

This indicates that the chances of the mean life span today is greater than 70 years is 0.5871

Step-by-step explanation:

The past year showed an average life span of 71.8 years.

$\mu = 71.8 years$

Population standard deviation = 8.9 years

$\sigma = 8.9 years$

We are supposed to find the mean life span today is greater than 70 years

i.e. P(X>70)

Formula : $Z = \frac{x-\mu}{\sigma}$

$Z=\frac{70-71.8}{8.9}$

Z=−0.202

P(X<70)=0.4129

P(X>70)=1-P(X<70)=1-0.4129=0.5871

Hence This indicates that the chances of the mean life span today is greater than 70 years is 0.5871

mrs. ranzoni made a sandwich that is 3 inches long and 5 inches wide. If she cuts the sandwich on the diagonal into 2 equal righ

Eddi Din [679]

Answer:

The length of Diagonal of the sandwich is 5.830 inches

Step-by-step explanation:

Given as :

The length of sandwich = 3 inches

The width of sandwich = 5 inches

Now, According to question , The sandwich is cut into to equal right triangle

So , As It become Right angle Triangle

∴ From Pythagoras Theorem

H² = P² + B²

Or, Diagonal² = 3² + 5²

Or, Diagonal² = 9 + 25 = 34

∴ Diagonal = √34 inches = 5.830 inches

Hence The length of Diagonal of the sandwich is 5.830 inches Answer

For a Chinese New Year celebration, James and Zhou are making a dragon costume similar to the one shown above.

Lilit [14]

Answer:

C. 24 meters

Step-by-step explanation:

Given:

Total length of fabric required for the costume = 56.6 m

Length of fabric Zhou already has = 15 m

Length of fabric James just purchased = 17.6 m

To find how much more length of fabric is required to make the complete costume.

Solution:

Let the length of fabric in meters still required be = $x$

The total length can be given as :

⇒ $(15+17.6+x)\ m$

⇒ $(32.6+x)\ m$

The total fabric required = 56.6 m

So, the equation to find $x$ will be:

$32.6+x=56.6$

Subtracting both sides by 32.6

$32.6+x-32.6=56.6-32.6$

∴ $x=24$

Thus, 24 meters of fabric is still required to make the costume.

Determine whether these two functions are inverses.

Lemur [1.5K]

Answer:

Yes,these two functions are the inverse of each other.

Step-by-step explanation:

They way of finding if two functions ( $f(x)\,\,and\,\,g(x)$ ) are the inverse of each other is by studying if their composition renders in fact the identity. That is, we see if:

$f(x) \,o \,g(x)=f(g(x))=x$

in our case:

$f(g(x))=\frac{1}{g(x)+4} -9\\f(g(x))=\frac{1}{(\frac{1}{x+9} -4)+4}-9\\f(g(x))=\frac{1}{\frac{1}{x+9} }-9\\f(g(x))={x+9} -9\\f(g(x))=x$

The composition does render the identity, therefore, these two functions are indeed the inverse of each other
