Okay but I'm like lowkey positive the answer is -1.14

y = -0.7x + 2.36
x = 5

y = (-0.7 x 5) + 2.36
y = -3.50 + 2.36
y = -1.14

Answer with explanation:

The Approximate line of best fit is given by the equation:

y = –0.7 x + 2.36

We have to find , value of ordinate that is y, when ,abscissa is 5.

Putting , x=5 , in the above equation ,to get the value of y

y = -0.7 × 5 + 2.36

= -3.5 +2.36

= -1.14

→None of the option.

if the equation has been like this

y = -0.7 x +0.36

y = -0.7 × 5 + 0.36

= -3.5 +0.36

= -3.14

Option A: -3.14

What value should go in the empty box to complete the calculation for finding the product of 62.834 × 0.45? A)2,213,360 B)2,313,

Aleonysh [2.5K]

Answer:

28.27530

Step-by-step explanation:

Given the expression 62.834 × 0.45, to solve this expression, first we need to convert it to fraction

62.834 = 62834/1000

0.45 = 45/100

Take the product if the resulting fraction:

62.834 × 0.45 = 62834/1000 × 45/100

= (62834×45)/1000×100

= 2,827,530/100,000

= 28.27530

Evaluate the expression using a calculator:

tester [92]

The value of the expression is 0.0265. Using exponents and power rules, the required value is calculated.

<h3>What are the exponent and power rules?</h3>

The important exponent and power rules are:

a⁻ⁿ = 1/aⁿ; negative exponent
(ab)ⁿ = aⁿ × bⁿ; power of a product rule
aⁿ × aˣ = aⁿ⁺ˣ; multiplication rule
aⁿ/aˣ = aⁿ⁻ˣ; division rule
$a^{\frac{x}{y} } = \sqrt[y]{a^x}$ ; fractional exponent

<h3>Calculation:</h3>

The given expression is $126^{-3/4}$

Using calculator: $126^{-3/4}$ = 0.0265

Applying the exponent rule for evaluating the given expression:

$126^{-3/4}$

Applying the negative power rule;

I.e., a⁻ⁿ = 1/aⁿ

⇒ $126^{-3/4}=\frac{1}{126^{3/4}}$

Applying fractional exponent rule;

I.e., $a^{\frac{x}{y} } = \sqrt[y]{a^x}$

⇒ $\frac{1}{126^{3/4}}=\frac{1}{\sqrt[4]{126^3} }$

⇒ 1/ $\sqrt[4]{2000376}$

⇒ 1/37.6077

⇒ 0.0265

Therefore, the value of the given expression is 0.0265.
