$67.50 for three pairs of pants. $97.50 for five pairs of jeans. For all of these the price would be $165.00

21. Carrie withdraws $10 from her account each day for 7 days.

Fiesta28 [93]

Answer:

a.70. b.50

Step-by-step explanation:

If Cartie takes $10 from her account for 7 days she would have taken $70 out.

$7 \times 10 = 70$

Next we look at the net problem it is asking us how much is left we already know from the equation above that we need to subtract 70 from 120
$70 - 120 = 50$
We now have both answers A. being that she would have taken $70 in total out of her account and B. being that she would have $50 left in her account.

The lengths of bolts in a batch are distributed normally with a mean of 3 cm and a standard

ValentinkaMS [17]

Answer:

0.8413 = 84.13% probability that a bolt has a length greater than 2.96 cm.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 3 cm and a standard deviation of 0.04 cm.

This means that $\mu = 3, \sigma = 0.04$

What is the probability that a bolt has a length greater than 2.96 cm?

This is 1 subtracted by the p-value of Z when X = 2.96. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{2.96 - 3}{0.04}$

$Z = -1$

$Z = -1$ has a p-value of 0.1587.

1 - 0.1587 = 0.8413

0.8413 = 84.13% probability that a bolt has a length greater than 2.96 cm.

Find the 6th term of a geometric sequence with t1=5 and r = -1/2

Hoochie [10]

In this item, we are to calculated for the 6th term of the geometric sequence given the initial value and the common ratio. This can be calculated through the equation,

An = (A₀)(r)ⁿ ⁻ ¹
where An is the nth term, A₀ is the first term (in this item is referred to as t₀), r is the common ratio, and n is the number of terms.

Substitute the known values to the equation,

An = (5)(-1/2)⁶ ⁻ ¹
An = -5/32

Hence, the answer to this item is the third choice, -5/32.

Consider f(x) = bx. which statement(s) are true for 0 < b < 1? check all that apply. the domain is all real numbers. the d

NeTakaya

The true statement for f(x)=b^x is the function is always decreasing function.

We have given,

f(x)=b^x where 0<b<1

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

Domain is all possible values of x for which any function is defined

We can select any values of x for which function

It will be defined for all real x

So, the domain is $(-\infty,\infty)$

The range is all possible values of y for which x is defined

we are given that b is positive

The value of the function will always be positive

So, the range is $(0,\infty)$

y>0

The x-intercept:

Set f(x)=0 and then we can solve for x

f(x)=b^x=0

x is undefined

The x-intercept does not exist

Increasing or decreasing:

Since, 0<b<1

The b is a positive value less than 1

As we increase the value of, $b^x$ will keep decreasing

This is decreasing function
