Yes

Direct variation because Time increases cupcakes increases and vice versa

Constant of proportionality represents the amount of time required per cupcakes

Yes we can find it

We have to check the x and y values of the ordered pairs (x,y)

If y is decreasing with respect to increase in x then it's inverse variation

A total of 135 seats, 118 front handlebars (that steer the bike) and 269 wheels how many bicycles, tandem bicycles, and tricycle

lesya692 [45]

Answer: There are 35 bicycles, 33 tricycles and 50 tandem bicycles.

Step-by-step explanation:

Since we have given that

Number of seats = 135

Number of front handle bars = 118

Number of wheels = 269

Since there are 118 front handle bars.

And we know that each bicycle has 1 front handle bars.

So, total number of bicycles = 118

Now, each bicycle has 2 wheels

So, Number of wheels should be

$118\times 2\\\\=236\ wheels$

But here we have 269 wheels , it means it has tricycle which has 3 wheels.

So, Remaining wheels would be

$269-236\\\\=33\ wheels$

It means 33 bicycles has 3 wheels .

So, Number of tricycles = 33

So, Number of bicycles should be now

$118-33=85$

Each bicycle has 1 seat

So, number of seats should be 85

But we have 135 seats,

So, remaining seats should be of tandem bicycle.

$135-85=50$

So, Number of bicycles now becomes

85-50 = 35

Hence, there are 35 bicycles, 33 tricycles and 50 tandem bicycles.

Human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°. Sally's temperature can be described by z = -

STALIN [3.7K]

Answer:

$97.27^{o}F$

Step-by-step explanation:

We have been given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°. Sally's temperature can be described by z = -1.5.

To find Sally's temperature we will use z-score formula.

$z=\frac{x-\mu}{\sigma}$ , where $\mu$ = Mean, $\sigma$ = Standard deviation.

Let us substitute our given values in z-score formula.

$-1.5=\frac{x-98.20}{0.62}$

Multiply 0.62 to both sides of equation.

$0.62\times-1.5=0.62\times \frac{x-98.20}{0.62}$

$-0.93=x-98.20$

Add 98.20 to both sides of equation.

$-0.93+98.20=x-98.20+98.20$

$97.27=x$

Therefore, Sally's temperature will be 97.27 degrees Fahrenheit.

What is mZU? •Not enough information given •30° •180° •75°

JulijaS [17]

It’s should be 30 if the triangle is drawn to scale

It would absolutely not be 180 because that’s the sum of all angles of the triangle

It could be 75 but if the triangle is drawn to scale then the two isosceles angle should be greater than angle U, so it won’t be reasonable if angle U is 75
