17.7 -> 177

19.1 -? ?

17.7177=19.1x

cross multiply

17.7x=19.1(177)

can you solve from there?

The cost to send 98 text messages will be $9.8.

What is mean by proportion?

A proportion is a fraction of a total amount, in which two ratios are set equal to each other.

Given that;

The cost of 177 text messages = $17.70

Now,

Since, The cost of 177 text messages = $17.70

So, The cost to send 98 text messages will be;

= $17.70 x 98 / 177

= $9.8

Thus, The cost to send 98 text messages will be $9.8.

An expression which represent his father's age three (3) years from now is: A. 3x + 15.

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

In order to write and solve this word problem, we would assign variables to the son's and father's age and then evaluate the resulting algebraic expression.

Translating the word problem into an equation, we have;

y = 4x

y + 2 + 3  = 3(x + 2 + 3)

y + 5 = 3(x + 5)

y + 5 = 3x + 15

Therefore, an expression which represent his father's age three years from now is 3x + 15.

In this case, the population consists of an insurance company's policyholders. The sample consists of his 200 policyholders under study. The sample size is 200.

H0: µ ≥ $5,000

Ha: µ < $5,000 (claimed)

As we can see that the sample size is 200, which is way greater than 30, so a z-test is appropriate here.

z(test) = (4800 - 5000) / (1300 / √200) = -2.1757

p (z = -2.1757) = 0.0148

The critical z-value for the left-sided test at α = 0.05 is -1.645

The tested value of z is less than the critical value, so we reject the null hypothesis. The hypothesis drawn here ( null hypothesis) will be rejected as an alternate decision because the p-value is less than the significance level (0.05).

At the 0.05 significance level, the prevention plan effectively reduced the average amount of harm. Insurers should continue these plans and try to improve them where possible.

The Magnitude of earthquake that hit Texas is 5.8; The logarithmic equation, in terms of exponents, so formed is: 74900 = [tex]30^M[/tex].

Given:

To find: Magnitude of earthquake that hit Texas.

Finding:

=>  [tex]\frac{I_2}{I_1}[/tex] =  [tex]30^M[/tex]

For  [tex]\frac{I_2}{I_1}[/tex] = 74900, the above expression becomes:

=> 74900 = [tex]30^M[/tex]

Taking logarithm on both sides, with base 10 gives:

=> log (74900) = log ([tex]30^M[/tex])

As [tex]log_b(a)^m = m(log_b(a))[/tex],

=> log (74900) = M ( log (30))

=> [tex]\frac{log(74900)}{log (30)}[/tex] = M

=> M ≈ 3.3, i.e., the increase in magnitude difference is approximately 3.3.

Thus, the magnitude of the earthquake that hit Texas = 9.1 - 3.3 = 5.8.

The logarithmic equation, in terms of exponents, so formed is: 74900 = [tex]30^M[/tex]

Hey there, your domain is all real numbers!! the graph is staying above the x-axis, but it's crossed from the negative x-values to the positive x-values. that means choice D is incorrect, because some of the function does cross through negative values.

if the domain was either of the inequality choices, the function wouldn't extend all over the graph--it would be ONLY between 0 and 5, or 5 and -5. this graph would be all real numbers because it isn't restricted like that.

The population of City C is 11.4 times the population of City A.

From the information, the populations of cities A and B are 3.6*10 to the 5 and 2,060,000, respectively

It was stated that the population of City C is twice the population of City B. That means the population of C will be:

= 2060000 × 2

= 4120000

Therefore, the population of City C is how many times the population of City A will be:

=4120000 / 360000

= 11.4

Therefore, the population of City C is 11.4 times the population of City A.

Shop A sells a dress for $79.50 with a 20% discount while Shop B sells the same dress for $69.50 with a 10% discount is $ 318 and $ 625.5.

The proportion of value in relation to the original value is measured using the percentage discount concept. In business, percentages are frequently employed to calculate a company's profit or loss percentage.

Let x be the actual cost of the dress in the store. A

20/100 ×x = 79.50 x = 79.50 ×100/20 xx = 7950/20

x = $ 397.5

The actual cost of clothing A is $397.5.

Discount of outfit A therefore equals 20%

$397.5-79.5$= $ 318

Let x represent the true cost of dress B.

(10/100)× x = 69.50$

x = $695

The actual cost of dress B is $695.

So, the dress B's discount is 10%.

$ 695 - 69.50 = $ 625.5
