Answer:

Positive correlation

Step-by-step explanation:

The correlation is weak, but it is definitely positive. You know this because as x increases to infinity, so does y.

If you needed to rate the correlation, it would be around a .7

In a hospital ward, there are 10 nurses and 6 doctors. 4 of the nurses and 3 of the doctors are male. If a person is randomly se

oksano4ka [1.4K]

Total number of people in ward = 16
Number of nurses = 10
Number of male nurses = 4
Number of female nurses = 6

Number of doctors = 6
Number of male doctors = 3
Number of female doctors = 3

We are to find the probability of selecting a female or a doctor.

Probability of selecting a female or a doctor = Probability of selecting a female + probability of selecting a doctor - probability of selecting a female doctor

Probability of selecting a female or a doctor = 9/16 + 6/16 - 3/16 = 3/4

Thus, the probability of selecting a female or a doctor is 3/4

Joan has earned grades of 88, 94, 92, and 98 on math tests so far. What must her next grade be to give her an average grade of 6

Ira Lisetskai [31]

Answer:

see the explanation

Step-by-step explanation:

Let

x ------> the next grade

we know that

To find the average grade sum the grades by the number of math test

$60=\frac{(88+94+92+98+x)}{5}$

solve for x

Combine liker terms in the right side

$60=\frac{(372+x)}{5}$

Multiply by 5 both sides

$300=372+x$

Subtract 372 both sides

$300=372+x$

$x=-72$ -----> this is not make sense

The grade cannot be a negative number

For x=0

The minimum average grade is

$\frac{(372)}{5}=74.4$

A Chef prepares and evenly divides s ounces of beef stock into 3 smaller pans. The chef uses 8 ounces of beef stock form one of

saw5 [17]

Answer:

Thus, the equation hat correctly represents the number of ounces of beef stock, $s$ , that the chef initially prepares.

⇒ $\frac{s}{3}-8=34$

The total number of ounces of beef stock = 126

Step-by-step explanation:

Given:

Total ounces of beef stock = $s$

The chef divided the beef stock evenly into 3 smaller pans.

The chef then uses 8 ounces from one of the smaller pans.

Ounces of beef stock left in the smaller pan = 34

Solution:

Total ounces of beef stock = $s$

Ounces of beef stock in each smaller pan = $\frac{s}{3}$

Ounces of beef stock used by the chef from the smaller pan = 8.

The ounces of beef stock left in the smaller pan will be given as:

⇒ $\frac{s}{3}-8$

Ounces of beef stock remaining in smaller pan = 34

Thus, the equation hat correctly represents the number of ounces of beef stock, $s$ , that the chef initially prepares.

⇒ $\frac{s}{3}-8=34$

Solving for $s$ .

Adding 8 both sides.

⇒ $\frac{s}{3}-8+8=34+8$

⇒ $\frac{s}{3}=42$

Multiplying both sides by 3.

⇒ $3\times \frac{s}{3}=42(3)$

∴ $s=126$

Thus, total number of ounces of beef stock = 126

Find the rational solution of x^3-3x^2+x+5=0. Show your use of the rational zero theorem to receive credit.

nasty-shy [4]

The rational root (or zero) theorem says a polynomial's rational zeros must have factors of the constant in the numerator and those of the leading coefficient in the denominator.

Here the leading coefficient is 1 and the constant is 5, so our only possibilities for rational roots are 1, -1, 5, -5

We try them each in term

1-3+1+5=6 nope

-1 -3 -1 +5 = 0 yes, x = -1 is a rational zero

5 and -5 don't work either so we're left with

Final answer: x = -1
