Jason owns a small business selling bagels. He knows that in the last week 45 customers paid cash, 8 customers used a debit card

tatuchka [14]

The probability that the next customer will pay with cash is 0.76

<h3>What is the probability?</h3>

Formula to find the probability of an event is:

P(A) = n(A)/n(S)

where;

n(A) is the number of favorable outcomes of an event A

n(S) is the total number of outcomes for an experiment/survey

We are given that;

45 customers paid cash

8 customers used a debit card

6 customers used a credit card.

Thus, the total number of customers:

n(S) = 45 + 8 + 6

n(S) = 59

Let event A be the event that the next customer will pay with cash. Thus, n(A) = 45

Therefore, the probability that the next customer will pay with cash would be;

P(A) = n(A)/n(S)

P(A) = 45/59

P(A) = 0.76

This is correct? I need help please :(

Answer:

well, we only no that

2l + 2w is 80

(lengths and widths on all 4 sides

and that w * l is A

so the function should be w times what's left for l, but also expressed by something with w

2l + 2w = 80 | -2w

2l = 80 -2w | devide by 2

l = 80 - w

now we can substitute l in

A = w * l

so that we only need w's

A(w) = w * (80-w)

for any w it will give us the area, makes only sense for 0<w<80

Enter a phrase for the expression

Nina [5.8K]

Answer:

The quotient of x and 11.

Step-by-step explanation:

Given:

$\frac{x}{11}$

Required:

Write the expression in words

Solution:

In the expression given, we have the numerator which is the dividend (x), and the denominator which is the divisor (8).

So, we are dividing x into 8 parts.

A quotient is the result you get when you divide the dividend by the divisor.

✅In describing the expression in words, we would use the following phrase:

The quotient of x and 11.

The dividend is mentioned first before the dividend.

-1/3+(-3/5)=

Illusion [34]

$\frac{-1}{3} + \frac{-3}{5}$
You need to use the equation for adding fractions, which is $\frac{a}{b} + \frac{c}{d} =(ad+bc)/bd$

In this case, a=-1, b=3, c=-3, d=5.

$
 \frac{(-1*5)+(3*-3)}{(3*5)}$

simplify

answer: $\frac{-14}{15}$

Answer:

p(-5/3) ≠ 0 So, (3 x +5) is NOT A FACTOR of p(x)

Step-by-step explanation:

Here, the given function is $p(x)=3x^5+2x^2 - 5$

Now, the given root of the function is ( 3x +5)

Now, if ( 3 x + 5) = 0,

we get x = - 5/3

So, the zero of the given polynomial is x = -5/3

Then, x = -5/3, p(x) =0 ⇒ ( 3 x + 5) is a FACTOR of p(x)

Now, let us find the value of function at x = -5/3

Substitute x = -5/3 in the given function p(x), we get:

$p(x)=3x^5+2x^2 - 5 \implies p(\frac{-5}{3}) = 3(\frac{-5}{3})^5 + 2(\frac{-5}{3})^2 - 5\\= 3(\frac{-3,125}{243}) + 2(\frac{25}{9}) - 5\\= (\frac{-3,125}{81}) + (\frac{50}{9}) - 5\\= -38.580 + 5.56 - 5 = -38.02\\\implies p(\frac{-5}{3}) = -38.02$

Now, as p(-5/3) ≠ 0 So, (3x +5) is NOT A FACTOR of p(x)
